Nvidia’s Deep Studying Tremendous Sampling, or DLSS, has grow to be a cornerstone function of contemporary PC video games. It began as a technique to increase your efficiency by rendering a recreation at a decrease decision, however the prominence and recognition of DLSS have prompted Nvidia so as to add much more options underneath the title.
At the moment, DLSS incorporates a number of completely different options, all of which leverage AI to spice up efficiency and/or picture high quality. It may be intimidating in case you’re a brand new RTX consumer, so I’m right here to interrupt down the entire will increase of DLSS in 2024 and how one can greatest leverage it in supported video games.
The numerous options of DLSS
I would like to determine this upfront — DLSS is an umbrella time period. In 2024, it includes a number of completely different options, all of which fall underneath the DLSS umbrella. Right here’s a fast rundown:
| Characteristic | DLSS model | GPU help |
| Tremendous Decision | DLSS 2.x and above | All RTX GPUs |
| Body Technology | DLSS 3 and above | RTX 40-series GPUs |
| Ray Reconstruction | DLSS 3.5 and above | RTX 40-series GPUs |
| Reflex | N/A | All RTX GPUs |
| DLAA | Elective; DLSS 2.x and above | All RTX GPUs |
In video games, you normally gained’t see the precise DLSS model. Fortunately, this info is on the market on the PC Gaming Wiki, and you should utilize a bit of deductive reasoning to determine the model of DLSS a specific recreation is utilizing. If the sport solely has Tremendous Decision or simply “DLSS,” it’s utilizing some model of DLSS 2. If Body Technology is on the market and Ray Reconstruction isn’t, it’s utilizing DLSS 3, and so forth.
This bundle of options can get complicated, however Nvidia places up guardrails relying on the GPU you could have. All RTX graphics playing cards help DLSS Tremendous Decision and Nvidia Reflex. Solely RTX 40-series GPUs, nonetheless, help Body Technology and Ray Reconstruction, along with Tremendous Decision and Reflex. If a recreation helps a function like Body Technology and your graphics card doesn’t, you gained’t be capable of activate the function in a recreation. On the flip facet, in case your graphics card helps a function like Body Technology and the sport doesn’t, you gained’t see the choice in any respect.
Let’s check out every of those options in a bit of extra depth.
Tremendous Decision
That is the core of DLSS, and in case you see a recreation that simply lists “DLSS” as an alternative of one of many particular options, it’s referring to Tremendous Decision. Tremendous Decision improves recreation efficiency by rendering your recreation at a decrease decision after which utilizing AI to upscale it. As an illustration, in case you’re taking part in a recreation on a 4K monitor, your graphics card could solely be rendering pixels for 1080p.
Tremendous Decision isn’t conventional upscaling within the sense that it simply copies neighboring pixels. As an alternative, Tensor cores on RTX GPUs run an AI algorithm to fill within the lacking particulars. This takes stress off your GPU, permitting your recreation to run at the next body price, and preserves as a lot picture high quality as doable.
Tremendous Decision is available in quite a lot of completely different modes that decide completely different render resolutions. Right here’s how they breakdown:
| DLSS mode | Render scale | Inner decision at 4K | Inner decision at 1080p |
| High quality | 66.7% | 2560 x 1440 | 1280 x 720 |
| Balanced | 58% | 2227 x 1253 | 1114 x 626 |
| Efficiency | 50% | 1920 x 1080 | 960 x 540 |
| Extremely Efficiency* | 33.3% | 1280 x 720 | 640 x 360 |
The three core modes of DLSS are High quality, Balanced, and Efficiency. The Extremely Efficiency mode is elective, so chances are you’ll not see it in each DLSS recreation. You’re protected with the core three modes. Naturally, Balanced appears to be like higher than Efficiency, and High quality appears to be like the very best, however all three modes are usable. I’d attempt them every out to see which one will get you to your efficiency goal, choosing the best high quality mode doable to succeed in your goal body price.
Your output decision — the decision in your show — influences efficiency and picture high quality fairly a bit. The efficiency advantages will probably be decrease at decrease output resolutions, and the picture high quality will probably be worse. At 4K, for instance, the Efficiency mode appears to be like nice. At 1080p, it’s a lot worse, each by way of picture high quality and efficiency.
Body Technology
Body Technology is just accessible on RTX 40-series GPUs in the mean time. It’s a separate setting you’ll discover in video games like Cyberpunk 2077, and you should utilize it with or with out Tremendous Decision. It’s a standalone function in supported video games. Not like Tremendous Decision, there aren’t high quality modes for Body Technology; it’s only a toggle.
Body Technology works by feeding an AI algorithm two consecutive frames. The AI appears to be like on the distinction between these frames and generates a brand new one to go in between. This occurs each different body with Body Technology turned on. Two frames are rendered and in contrast; the AI generates a body in between after which strikes on to the following set of two frames.
With Body Technology, you’re taking part in on a delay. As a result of the AI wants two separate frames, there’s a backlog of frames that aren’t displaying up in your display immediately. The delay isn’t large — a handful of milliseconds — however it’s sufficient that Body Technology requires Nvidia Reflex (extra on that quickly).
There are occasions when Body Technology is problematic, nonetheless. It doesn’t enhance your recreation’s responsiveness; it simply makes your recreation look smoother. Due to that, in case you’re utilizing Body Technology to take a recreation from 30 frames per second (fps) to 60 fps, it’ll nonetheless really feel such as you’re taking part in at 30 fps. This impact is minimized the upper your preliminary body price is, so it’s greatest to make use of Tremendous Decision and Body Technology collectively.
Ray Reconstruction
Ray Reconstruction is the latest addition to the DLSS lineup, and it’s solely accessible for RTX 40-series GPUs. It’s solely accessible in two video games on the time of writing, too — Alan Wake 2 and Cyberpunk 2077. Though I believe extra video games will help Ray Reconstruction sooner or later, it gained’t be a mainstay like Tremendous Decision and Body Technology.
Tremendous Decision and Body Technology are centered on bettering efficiency, however Ray Reconstruction is targeted on bettering picture high quality. It’s an AI-powered denoiser for ray tracing. That’s a variety of technical jargon, and there are a variety of technical particulars to the function, however in observe, Ray Reconstruction makes use of AI to make ray tracing results extra correct.
This doesn’t influence efficiency, no less than within the two video games the function is on the market in, and it may well really enhance efficiency relying on the scene. Like Body Technology, Ray Reconstruction is a toggle; there aren’t a number of modes. Nevertheless, it is probably not accessible relying in your graphics settings. In Cyberpunk 2077, for instance, Ray Reconstruction is just accessible with the RT Overdrive graphics preset.
Reflex
Reflex isn’t technically a part of DLSS, however you’ll see it alongside DLSS options rather a lot. It synchronizes the connection between your CPU and GPU in order that neither part is ready on the opposite to render a body. This reduces general system latency, making your video games really feel extra responsive. It’s a toggle like Ray Reconstruction or Body Technology.
Reflex is generally centered on esports titles, however it’s been swept up into DLSS with the introduction of Body Technology. Because of the further latency attributable to Body Technology, you possibly can solely use the function with Reflex turned on. In practically each recreation, turning on Body Technology will mechanically activate Reflex, and also you gained’t have the choice to show Reflex off.
DLAA
DLAA stands for Deep Studying Anti-Aliasing, and it’s an possibility you’ll solely discover in a handful of DLSS titles like Diablo IV. It’s one of many high quality modes you’ll discover amongst Tremendous Decision, and as an alternative of working your recreation at a decrease decision, it runs your recreation at native decision.
The AI-driven anti-aliasing inherent in DLSS Tremendous Decision is basically good — so good, in truth, that turning on DLAA will make your recreation look higher than simply native decision. It’s a terrific possibility if the sport you’re taking part in helps DLSS and also you’re already getting nice efficiency out of your PC with Tremendous Decision turned off. Diablo IV is a superb instance, the place DLAA appears to be like glorious.
Methods to get probably the most out of DLSS
DLSS is on the market in a whole lot of video games, and that record is just rising. If in case you have an RTX GPU, you’ll in all probability activate no less than some options of DLSS, particularly in demanding titles like Alan Wake 2 and Cyberpunk 2077. Right here’s learn how to get probably the most out of the function set.
Maintain your decision in thoughts
As talked about, DLSS Tremendous Decision works greatest at a excessive output decision. It appears to be like and performs greatest in case you’re outputting at 1440p or 4K, and the advantages diminish at a decrease decision like 1080p. There are a few causes for that.
First, efficiency. When you could have a decrease output decision, DLSS will render your recreation at an excellent decrease inside decision. This could create a CPU bottleneck as you go right down to lower-quality modes. In observe, that would imply you’re utilizing a top quality mode that appears worse with out offering any efficiency profit.
If you happen to’re working at a low decision like 1080p, all the time begin on the High quality preset earlier than transferring down. In lots of instances, you’ll discover a small efficiency enchancment at Balanced and nearly none at Efficiency.
Picture high quality can be an element at decrease resolutions, similar to 1080p. As you progress down the standard modes, you’re successfully giving the AI algorithm much less info to work with. At a excessive decision like 4K, this isn’t an issue, because the algorithm already has loads of info, even with DLSS’ Efficiency mode. That very same isn’t true at 1080p, and the extra demanding high quality modes can stretch the bounds of what DLSS is able to.
Begin with a excessive base body price
If you happen to’re utilizing DLSS Body Technology, you should begin with a excessive base body price. I like to recommend getting your recreation working at 60 fps no less than by means of a mixture of graphics settings and Tremendous Decision earlier than turning Body Technology on.
That suggestion comes right down to how Body Technology works. As talked about, it’s a expertise that helps your video games look smoother, not really feel smoother. There’s a visible advantage of a excessive body price in PC video games, however the principle motive you need a excessive body price is healthier responsiveness. Body Technology does nothing to enhance responsiveness, and as a consequence of how the expertise works, it may well really make responsiveness barely worse by itself.
Body Technology works greatest on prime of a excessive base body price, pushing one thing from 60 fps to, for instance, 100 fps. You shouldn’t apply it to its personal in most conditions.
Generally DLSS appears to be like higher
You might not want to make use of DLSS in much less demanding titles, even when they help the function. There are undoubtedly instances the place DLSS could make a recreation look higher. That’s the concept behind DLAA within the first place — the AI-assisted anti-aliasing in DLSS appears to be like incredible. In video games the place you’re already getting good efficiency, attempt turning on DLSS to High quality mode and see the way it appears to be like.
It’s doable, particularly in video games that solely use Temporal Anti-Aliasing (TAA), that DLSS set to High quality mode will look higher than native decision. It’s counterintuitive, however the anti-aliasing inside DLSS is commonly higher than TAA in video games, so higher-quality modes at larger resolutions can look higher with DLSS on.
Going past DLSS
If you happen to weren’t conscious, DLSS is open supply now, and it’s sprung a relatively sturdy group of modders hacking and altering the function in video games. One of the vital highly effective instruments accessible is DLSSTweaks, which is a free, open-source undertaking that may add further DLSS options to video games and alter the model.
What DLSSTweaks is basically good at is setting customized scaling. DLSS Tremendous Decision has just a few mounted scaling ratios by means of the presets. DLSSTweaks permits you to customise the ratio, as much as 100% of the native decision. That basically offers you entry to DLAA in video games that don’t natively have the choice, similar to Lies of P, Crimson Lifeless Redemption 2, and Atomic Coronary heart.
DLSSTweaks carries a few caveats. The primary is that it doesn’t work with each recreation. The GitHub web page maintains an inventory of titles that work, however you continue to could run into points. Moreover, because you’re modifying recreation recordsdata, you shouldn’t use DLSSTweaks in on-line video games.
Most significantly, DLSSTweaks can’t add DLSS options that aren’t in a recreation. Newer variations of DLSS could have a barely higher high quality of efficiency, but when a recreation doesn’t help Body Technology, for instance, DLSSTweaks can’t add it.
There are mods that add Body Technology into video games. Probably the most well-known modder is PureDark, who has added DLSS 3 and FSR 3 to numerous titles, together with Starfield and Palworld. Modder LukeFZ has quite a lot of these mods accessible, as nicely. Some video games have free DLSS Body Technology mods, whereas others come by means of a paid Patreon subscription. Regardless, there are alternatives so as to add DLSS Body Technology to video games that don’t have it by default.
Though DLSS began as a distinct segment upscaling function, the time period has grown to embody a far higher record of options. Most fashionable video games will help some mixture of DLSS options, and in case you personal an RTX GPU, it’s best to in all probability reap the benefits of them — that’s one of many major causes to purchase an Nvidia graphics card, in any case.
