          Ultrawide monitors are displays with a 21:9 aspect ratio, offering more horizontal screen space than a standard 16:9 monitor without increasing the screen height. Although ultrawide monitors aren’t the most common type of display, they’re popular among gamers who want an immersive experience. You can see more of your surroundings in games without constantly having to pan around, and they’re extremely well-suited for FPS or atmospheric games. Most ultrawide gaming monitors have 34-inch screens, but finding the perfect solution for your needs depends on your budget.

          We’ve bought and tested over 275 monitors, and below are our recommendations for the best ultrawide gaming monitors to buy. See our recommendations for the best curved gaming monitors, the best ultrawide monitors, and the best 34-49 inch monitors.

            See all our test results

            The best ultrawide gaming monitor we’ve tested is the Dell Alienware AW3423DW.  Gaming feels excellent thanks to its near-instantaneous response time that results in almost no motion blur. It has a 175Hz refresh rate with native G-SYNC variable refresh rate (VRR) support to reduce screen tearing, meaning it can take full advantage of your NVIDIA graphics card. If you have an AMD graphics card, the Dell Alienware AW3423DWF is a cheaper model with native FreeSync support instead. However, keep in mind that OLEDs are prone to burn-in with constant exposure to the same static elements over time, like with HUD elements in your game if they’re on the screen all the time, but it isn’t a major concern if you’re playing different games.

            It uses QD-OLED technology that offers perfect black uniformity and remarkable picture quality. It performs best in dark rooms because it displays deep and inky blacks without blooming. However, bright light sources cause black levels to raise, so blacks aren’t as deep and inky in bright rooms as in dark rooms. Luckily, it’s also a fantastic HDR gaming monitor thanks to its bright highlights and wide range of vivid colors.

            If you tend to play atmospheric or FPS games and want the most screen real estate possible, look into the Samsung Odyssey Neo G9, which has a super ultrawide screen. It’s an excellent gaming monitor with a 32:9 aspect ratio and 5120×1440 resolution, which is even bigger than typical ultrawide monitors like the Dell Alienware AW3423DW. It’s the equivalent of placing two 27-inch, 1440p monitors next to each other, letting you see more of your game at once.

            Instead of the remarkable dark room picture quality of the QD-OLED Dell monitor, it uses Mini LED backlighting to get extremely bright, which is great for HDR gaming, as highlights stand out. In terms of gaming features, it has native FreeSync support, G-SYNC compatibility, and a fast 240Hz refresh rate, meaning you can play games at a high frame rate without issue. The motion handling is also great no matter the refresh rate you’re gaming at, and it has a backlight-strobing feature to reduce persistence blur. It also has low input lag that makes gaming feel responsive.

            See all our test results

            If you don’t need the best performance possible, an upper mid-range option like the LG 34GP83A-B is a good alternative. It’s much smaller than the Samsung Odyssey Neo G9, at 34 inches and with a 21:9 aspect ratio, so it’s more of a cheaper alternative to the Dell Alienware AW3423DW. It’s different from the Dell because it has an LED-backlit LCD panel, meaning the picture quality is worse as it can’t display perfect blacks, but you also don’t have to worry about the risk of burn-in with it.

            This monitor’s fantastic motion handling makes it special for gaming, especially with signals at a high refresh rate. It results in minimal motion blur, but the monitor doesn’t have a backlight-strobing feature to further reduce persistence blur for games at a low refresh rate. It also has FreeSync VRR support to reduce screen tearing and is G-SYNC compatible. However, if you have an NVIDIA graphics card and want something with native G-SYNC support, the LG 34GP950G-B performs similarly but costs more.

            See all our test results

            While there are some other options priced in the mid-range category, like the Dell S3422DWG or the AOC CU34G2X, the Gigabyte M34WQ is a great budget ultrawide gaming monitor that offers better performance than the Dell or AOC for a lower cost. Instead, it has similar features to the LG 34GP83A-B with worse overall gaming performance as you can’t overclock its 144Hz native refresh rate up to 160Hz, and motion looks worse on it. It has a slower response time, leading to more smearing, especially when gaming at low refresh rates.

            It has a flat screen instead of a curved one like on the LG, so the edges are outside your field of vision and can look washed out if you sit too close. However, it’s a good choice for co-op gaming as it offers swivel adjustment, which the LG doesn’t have, and it still has wide viewing angles, so the image looks consistent from the sides. It’s a great gaming monitor as it has native FreeSync VRR support to reduce screen tearing, and even though it isn’t certified by NVIDIA, G-SYNC compatibility works with NVIDIA graphics cards. Its input lag is also low for a responsive feel while gaming.

          Today’s best Asus ROG Swift PG42UQ deals





          Though OLED isn’t quite ready to claim desktop dominance from LCD on the best gaming monitors, more products are entering the pipeline. These new introductions mean more choices and, hopefully, lower prices. One obstacle to wide acceptance has been size. Early OLED computer monitors weren’t much smaller than big-screen TVs, making them difficult to integrate into an office-sized productivity and entertainment system.

          Asus has made a step towards progress with its new 42-inch OLED display, the ROG Swift PG42UQ. Like all new genres, the first products are premium (read: expensive) items, but there is a lot to like. The PG42UQ delivers 4K resolution with an overclocked 138 Hz refresh rate, Adaptive-Sync, HDR10 and extended color. A special screen layer keeps the image bright and colorful under typical room lighting. In addition, a large array of connectivity options makes it suitable for various configurations, including computers, consoles and streaming boxes.

          • Asus ROG Swift PG42UQ at Amazon for $1,512.10

          I hesitate to use the words “typical OLED” considering there are so few available outside the television genre. However, the PG42UQ is not a typical OLED monitor because it employs a special screen layer that Asus calls “anti-glare micro texture coating.” In my observation, this is another term for a polarizer. While this is nothing new – all OLEDs have some form of polarization – Asus’ approach specifically targets one of the downsides of using an OLED TV as a monitor, ambient light reflection. Large screen OLED TVs almost always have a shiny front layer that has great optical clarity but poor handling of reflections. The PG42UQ keeps that optical advantage but also prevents light from spoiling the image when it hits the screen at an angle. There’s usually a downside, but it’s minor, and I’ll talk about it on page two.

          The PG42UQ delivers a practical 450 nits peak for HDR and unmeasurable black levels. Asus claims 1.5 million to one contrast, but in practice, it is infinite because it can’t be measured by any instrument. OLED panels have a visual quality that simply cannot be duplicated by an LCD of any type.

          The color gamut is wide, covering nearly 94% of DCI-P3 in my tests. I’ve measured two other screens that top 100% from Aorus and Alienware, but visually, the PG42UQ is stunning. A factory datasheet guarantees color accuracy, and I confirmed this. You won’t need to calibrate this monitor.

          HDR10 is supported over both HDMI and DisplayPort, and the panel has a native 10-bit color depth. Asus provides three HDR modes and adjustable brightness, which most HDR monitors do not offer.

          Gaming cred comes from a 138 Hz refresh rate achieved via an overclock setting. That gives the PG42UQ a slight edge over other 4K OLEDs, which top out at 120 Hz. Of course, lower-resolution WQHD can provide 165 Hz and 240 Hz. Adaptive-Sync comes in the form of Nvidia G-Sync and AMD FreeSync certification. And with a claimed 0.1 ms response time, motion blur should be non-existent.

          Extras include Asus’ GamePlus array of gaming aids like aiming points, frame counter and timers. The panel also has a quarter-inch tripod mount socket at the top, with a USB port nearby, for webcams and other compatible peripherals. Two additional USB 3.2 ports underneath let you plug in your gear. 10-watt amps drive the built-in speakers and there’s an additional 15-watt subwoofer inside to round out the bass.

          Assembly and Accessories 

          The PG42UQ is a premium experience from the moment you lift off the outer carton. The cable bundle comes in a nice fabric zippered bag and includes DisplayPort, HDMI and USB along with a remote control and an IEC cord for the internal power supply.

          The base bolts on with four included fasteners and here, I had an interesting experience. The bolts are Allen rather than the usual Phillips; try as I might, I could not find an Allen key anywhere in the package. I retrieved a 3 mm tool from my garage and attached the stand. I discovered an Allen key clipped inside when I removed the input panel cover. Someone at Asus actually took the time to engineer this molded part to include Allen key storage. I call that attention to detail though I’d rather the Allen key were simply bagged with the fasteners. You just have to remove the input cover to find it.

          One of the great things about OLED monitors is how thin their bezels can be. The PG42UQ measures just 6mm around the top and sides and 10mm at the bottom, flush, of course. The panel isn’t super thin, but it is slimmer than the same-sized LCD at just 1.5 inches. If you’d rather mount it, the VESA lug pattern is 300 mm, which you’ll find in TV brackets. With a panel-only weight of nearly 30 pounds, an arm probably won’t work.

          Under the input cover, you’ll find four HDMI ports, two 2.0 and two 2.1, along with a DisplayPort 1.4 that supports Display Stream Compression (DSC) and 10-bit operation. Headphones plug into a 3.5mm jack and there’s an optical digital (S/PDIF) port so you can hook the PG42UQ up to an AV receiver or surround processor in a home theater application.

          At the top, you’ll find a quarter-inch tripod socket with a rubber surround and a USB port, perfect for installing a webcam. The back is conservatively styled for Asus and features a simple pattern of molded-in lines plus the ROG logo. There is no dramatic LED lighting here, only a glowing logo in front which can be switched off if desired. The stand is a TV-style affair made from cast aluminum. It’s plenty deep enough to keep the panel steady and features five degrees tilt either forward or back. The back tilt is perfect for the average desktop as the panel is elevated just three inches. Underneath the glowing logo is an OSD joystick along with keys for power and cancel. The grilled protrusions on either side house the speakers, 10 watts each, plus an internal 15-watt subwoofer. The sound quality is very good, with plenty of clarity, volume and decent bass.

          If you’d rather not reach out to adjust the PG42UQ, an included handheld remote covers all monitor functions. It’s infrared-based, so you’ll have to point it at the logo in the bottom center. The OSD can be made large enough to be read from eight to ten feet away.

          OSD Features

          Pressing the joystick or remote select key opens a comprehensive and well-organized OSD. The directional keys can also be programmed to provide quick access to various functions.

          Asus always prioritizes gaming modes, and the first thing you’ll want to do is switch on the PG42UQ’s overclock and turn the action up to 138 Hz. It was reliable with no hiccups during our time with the monitor. GamePlus offers an array of play aids, including a frame counter, aiming points, sniper mode, countdown timer and a stopwatch. The sniper mode magnifies the center of the screen anywhere from 1.2 to 2 times larger with a colored dot to help with aiming.

          There are eight picture modes, including Racing, the default, sRGB for color-critical work and a User mode. Racing can be calibrated to a high standard though it is already visually perfect out of the box. You can also pick the color gamut without engaging sRGB if you wish. The Shadow Boost feature makes dark detail easier to see and has five fixed levels and a dynamic option.

          In the Image menu, you’ll find a checkbox called Uniform Brightness, which is important. It’s off by default, meaning the panel will vary in brightness depending on the average picture level. In vintage parlance from the era of CRT, we called this “DC restoration.” It is a process that keeps a display’s power supply from overloading when the picture has a lot of bright content. Modern-day plasmas and OLEDs still employ this to be more power efficient and to preserve the panel’s lifespan. If you check the box, the picture will not change brightness, but it will be about 50% darker. While this could be considered a more purist way to run the PG42UQ or any OLED, it is not an attractive option. I recommend leaving the box unchecked for the best possible image under all circumstances.

          In the Color menu, you’ll find calibration options that include two color spaces, color temps by Kelvin value with user mode, and gamma presets. If you simply leave the PG42UQ in Racing mode, you won’t need to change anything here unless you want sRGB. That’s easy to engage without disturbing other parameters.

          The joystick and remote nav pad can be programmed for various shortcuts like brightness, volume, input, GamePlus and more. The remote has two additional keys that the user can also program.

          Asus has included three panel care options to preserve the life and quality of the PG42UQ. A screen saver can be set to come on after a period of inactivity. Pixel Cleaning is a process that refreshes the entire screen to equalize pixel use and prevent burn-in. Once initiated, it takes about six minutes to complete. Screen Move is an orbiter that shifts the image by a few pixels. Adjust Logo Brightness dims the lower right corner of the screen to prevent burn-in from channel logos.

          Asus PG42UQ Calibration Settings

          The PG42UQ’s Racing mode proved spot-on in my tests, with no visible errors in grayscale, gamma or color gamut tracking. I calibrated the User color temp and made a tiny improvement that only the meter could see. The sRGB mode is also very accurate though it is just as easy to stay in Racing and choose sRGB from the Color Space menu. Feel free to try the settings from my tests listed below.

          In HDR mode, there are three options, Game, Cinema and Console. Game is the default and best choice, with good luminance tracking and bright vivid color. You can activate the brightness control to dial down the image for dark room playing.

           Gaming and Hands-on

          If you’ve been considering the purchase of a large desktop monitor, the PG42UQ should be added to your short list. I’m a fan of the 32-inch size and now I’m a fan of 42. You’ll need to allow a bit more room for it, but the image here is so sharp and vibrant, it’s worth the effort of clearing other objects from the workspace.

          Large, curved panels are a great way to immerse yourself in a game or movie, but large flat screens can do the job nearly as well, thanks to their prodigious height. Sitting between three and four feet away filled my peripheral vision completely and replicated the experience of sitting close to the screen in a movie theater. I appreciated the PG42UQ’s tilt function, which let me position the screen to put everything in focus. The panel sits three inches off the desktop and can’t be raised.

          Opening three or four documents on the screen is completely practical here. Windows defaulted to 300% font scaling, which is great if you sit further back. At my closer viewpoint, 150% was a better choice. Sharpness was never an issue, and I could not see the pixel structure. For a near-field application like this, 42 inches is an ideal size for 4K resolution. Pixel density is 106ppi, close to the 109ppi of a 27-inch QHD panel. It’s perfect for text and graphics.

          When an OLED and LCD are calibrated to the same brightness and placed side-by-side, you can always pick out the OLED, thanks to greater contrast. Even the best Mini LED panels can’t reproduce intra-image black levels like an OLED. That gives it an extra glow and vibrance and immediately sets it apart.

          It’s inevitable that a 42-inch monitor will be used to watch TV and movies, so I hooked up an Apple TV 4K and a 4K Blu-ray player. The PG42UQ worked flawlessly with all frame rates, 24, 50 and 60 fps, and provided artifact-free video processing with clean scaling of 1080p material. It also had no problem with HDR10 content though I found HDR color to be a bit less saturated than the Aorus FO48U or the Alienware AW3423DWF ultra-wide panel. However, it was still punchier than SDR.

          I rarely talk about gaming monitor audio because the physical limitations of small panels mean tiny speakers that play a narrow range of frequencies. The PG42UQ has more room and Asus has taken advantage. The internal stereo speakers and subwoofer deliver truly impactful sound that blows away any computer monitor and most TVs I’ve experienced. Good audio makes a real difference in the gaming experience.

          Gameplay is an absolute joy on any OLED, thanks to super-clean motion processing. With no need for overdrive or backlight strobes, the PG42UQ could easily maintain sharpness during the fastest camera pans, mouse movements and circle strafes. I mowed through enemies easily in Doom Eternal and Call of Duty WWII. Response was instantaneous with no perception of input lag. I couldn’t quite get to 138 fps without reducing detail levels, but at 120 fps, I had the same experience as I would on a 165 Hz LCD. OLED enhances gameplay by making more of a given refresh rate.

          HDR provided deep contrast with a bright picture that was never harsh. I did not regret leaving the brightness slider maxed for all content. I also confirmed that Game HDR was the best mode for all HDR applications, games and videos. The PG42UQ is a very addicting monitor. If you try one in a store, you’ll want to take it home.

          Sect of witnesses 144 Hz and ultra-wide formats / Sudo Null IT News

          There are key points in the life of a PC user that change their attitude to what is “under the hood” or before their eyes. Someone discovers Windows 10 or Linux, someone realizes that they managed to assemble the coolest gaming machine in a Mini-ITX case, which is still not heard at night. This also includes a 4k monitor (especially with a small diagonal and a hell of a pixel density) SSD, some SLI or Crossfire, 32-64 giga of RAM … Something insanely happy and makes you live with a smile at all 32

          gigabytes teeth, something leads to disappointment.

          Own “Wow, cool!” I regularly update one way or the other. More than five years ago, my old 27-inch Samsung with a resolution of 2560×1440 seemed incredible to me, then I got acquainted with 144Hz monitors and G-sync, managed to chat with 21 to 9 super widescreens, curved displays and other joys of life. Today I have a monitor on my desk that combines a number of such goodies. 35″, 21:9, fantastic 160Hz refresh rates and a curved display. And while his permission doesn’t make you shed a tear and say “yes, you’re my dream,” he’s still damn good, and here’s why.

          He is demonically fast

          No, I am absolutely seriously convinced that it is hard to explain in words how 60 Hz differ from 160. Some stubbornly do not see the difference between console 30 FPS and PC’s 60+, but here it is. Take some bright window for the title, and shake it with the mouse well. Now imagine that you do not see the “traces” of the window, that it will be almost perfectly clear all the time. There are no traces, the maximum is a light plume, which is due to the speed of the reaction of neurons in the eye.

          There is only one utilitarian application for such a refresh rate: computer games. Yes, even at the OS level, it is more convenient / pleasant / less tired to use the eyes, but in dynamic and reaction-sensitive games, 120 or 144 Hz already give a lot, and 160 is a kind of “margin of safety” that allows you not to run into V-Sync and get MORE SMOOTHNESS.

          Fortunately, the monitor supports the FreeSync adaptive synchronization system: it was originally incorporated into the DisplayPort standard and later found its implementation in AMD video cards. Unfortunately, NVIDIA decided to play Apple and leave their curve is a proprietary standard on which it successfully cuts loot by selling special chips to monitor manufacturers. Alas, a strange situation awaits us in the near future: there will be more and more monitors with FreeSync in the world with the total dominance of NVIDIA in the video card market, despite the fact that NVIDIA simply does not support this feature. It’s a shame.

          Both basic algorithms, FreeSync from AMD, G-Sync or Adaptive fast sync from NVIDIA, when the frame rate exceeds the maximum allowable for the sweep, start to “throw out” extra frames in the same way, which causes related problems that only nerd e-sportsmen really worry about .

          21 to 9 drags

          Yes, many toys are completely not optimized for this resolution. In the same Diablo 3, you will see terrible, peeled backs. In some old Need for Speed, the speedometer interface will turn from a circle into an ugly oval. Old school stuff can crash in general, you have to play in a window or tell your monitor to pretend to be normal 16 to 9. But everything changes when you run something modern. Something… that really feels different on the big screen. Let’s say DOOM from 2016, The Witcher, the latest NFS or Project Cars. Yes, even the EuroTruckSimulator, which does not shine with graphics, an arcade platformer, a Starbound-type sandbox or some kind of MOBA, is perceived quite differently. You see further than your opponents. The vertical scale remains the same, but the view to the left and right (forward and backward, call it whatever you like) is growing. I think it’s too much to describe the benefits. In racing, you see more, in shooters you notice the enemy earlier (especially if you adjust the FOV).

          Anyone who plays car simulators knows that over time on the same track and car you set some average time that is hard to beat. It seems to slow down at ideal points, enter the turn on time, where necessary – let the rear axle into a skid or fly within millimeters of the chicane fence. So: with this monitor, I brought myself 4 seconds from the very first attempt. Of course, both the increased frame rate and the increased viewing angle play a role here, but the fact is the fact.

          In everyday use, such a monitor to some extent replaces two ordinary ones: browser windows side by side, messengers in a bunch, panels in a graphics or 3D editor that do not obscure the work area, which turns into approximately a standard 16 to 9 – in general, a lot of pluses. Working with several texts at once is generally gorgeous. Open code listing, help, browser and bug tracker on one screen and keep everything in view? Well, you understand. Any task with a bunch of windows is sorted into neat columns.

          Also, those $@!% black stripes on the top and bottom are finally gone from the movies. Now you can watch modern blockbusters in normal size.

          It’s curved!

          Here is laughter with laughter, and you can understand the charm of a curved monica after a week of use. You sit down at some “flat” of comparable width, and it seems convex, like an old TV. This effect lasts for several hours, but at first you sit with a strange feeling “something is wrong here.” Immersion in the process in terms of toys is also different, peripheral vision in humans plays a rather important role in determining movement. Those who have 2-3 monitors according to this scheme will understand me.

          Picture from the Internet

          Competing with three monitors will not work, but there is a similarity of sensations. I had experience with “flat” 21 to 9, and the curved version, IMHO, is much more interesting.

          What exactly is it about

          The device that I described is a 35-inch AOC with the index C3583FQ. Its full characteristics are as follows:

          Diagonal: 35 inches;
          Sensor: AU Optronics, VA technology, matte finish;
          Panel curvature: 2000R 1 ;
          Resolution: 2560×1080 pixels;
          Max. refresh rate: 160 Hz 2 ;
          Connection interfaces: DP 1.2, HDMI 1.4, DVI-D, VGA.

          1 – 2000R indicates that the curvature corresponds to a section of a circle with a radius of 2 meters;
          2 – The maximum refresh rate is achieved only when connected via DisplayPort.

          The monitor has some nice features that I would like to see from other manufacturers for a long time. All ports are placed in a stand. No more “beard” of wires hanging from behind the monitor, everything can be neatly removed either over the edge of the table or in a neat braid and folded / secured with zip ties.

          The only thing I would add in this scenario is a USB hub with ports sticking out to the user. It would be perfect for some flash drives or peripherals. And certainly much more useful than scanty and miserable speakers, which … well, let’s just say, do not give out any decent sound at a not very modest price of the device and a very specific target audience, which does not need them.

          Horizontal rotation, as well as the ability to make the monitor vertical for obvious reasons, is not, but the lack of height adjustment upsets. The angle of inclination is given to choose – and then bread. Although, as for me, the monitor turned out to be low, and it will feel comfortable on some shelf, the width of the entire table, so that both the keyboard and the mouse can be hidden under it. And you can’t hang it on the wall. Trouble, trouble, grief. Oh yes. The control buttons are located quite far from the menu and in general it is … eccentric. But I’ve only seen normal menus on professional monitors, so it’s just a sad norm on the market, to write crooked and ugly built-in software.

          The VA-type matrix does not give the monitor a miraculous response of 1-2 ms, but is a reasonable compromise between acceptable color reproduction, speed of operation and provided viewing angles. VA technology provides good image contrast, refresh rate, like classic (not super-gaming) TNs at the level of 4-6 ms. The color reproduction is far from ideal and will not allow using the monitor for professional purposes, but it is quite acceptable for a home-gaming model. The base white point is at the level of 6250-6300 Kelvin (with a standard value of 6500K), the contrast ratio is at the level of 1700 to 1 at a brightness of 395-400 nits

          But he’s not a retina!

          Do not rush to scold the model for its low resolution and not the strongest bend, there is a rational explanation for everything. Let’s start with the bend. Yes, the “ideal” convergence, for which the screen will seem completely flat to a conditional observer – two meters, but the peculiarities of human vision, as well as the fact that you can sit at the monitor together in the evening (for example, watch a movie) makes manufacturers take a slightly larger radius for curvature. And the technology for manufacturing such matrices still has some limitations.

          Now to the resolution. 2560×1080 was chosen for two reasons. The first is that to ensure a refresh rate of 160 Hz, an impressive bandwidth of the connection channel is required. Of all the presented connection standards in the monitor, the maximum is DisplayPort 1.2. At a resolution of 3840×1440, it is difficult to squeeze out more than 100 Hz, and 120, 144, 160 Hz can only be provided for 2560×1440 and 2560×1080. Since the DP 1.3 standard is not widely used, and ports with version 1.4 have become available since March of this year, the choice of interface seems quite logical.

          The second reason for this particular resolution is a reasonable compromise on the load on the video card: if your model provides sufficient performance for FullHD resolution, then the additional load and so-so optimization in some toys will not become an unbearable burden for the current generation of hardware: a confident frame rate in “competitive” The titles will be provided by the old GTX 970 (and according to STEAM this is the most popular video card in the gaming world at the moment), and something like the GTX 1060 6GB. Even a 1050Ti or RX470 can handle it if the settings are cut to medium-high.

          Do you need an upgrade?

          How much does an increase in resolution along one axis by some 640 points affect performance? The resolution of 1920×1080 gives a little more than 2 million pixels of the resulting image, 2560×1080 – already 2.7 million. That is, according to rough estimates, performance will drop by about 35%, since the video card has to calculate 1.35 times more pixels for each frame. In reality, the drop in performance can be either smaller (due to the peculiarities of the operation of drivers and the construction of the scene by the video card), or significantly larger (no one canceled the profiling and polishing of the game engine, but 21 to 9so far extremely rare cases to bother much with optimization).

          For comparison: the average 60 FPS on the GTX 1060 6GB in the third part of The Witcher (all settings at maximum with Hairworks enabled) turns into 40-45.

          And DOOM, with its state-of-the-art engine, almost doesn’t care: 60 FPS turns into 55.
