Nvidia’s Deep Studying Tremendous Sampling, or DLSS, has turn into a cornerstone characteristic of contemporary PC video games. It began as a approach to increase your efficiency by rendering a sport at a decrease decision, however the prominence and recognition of DLSS have prompted Nvidia so as to add much more options beneath the identify.

As we speak, 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 should 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 ascertain this upfront — DLSS is an umbrella time period. In 2024, it contains a number of completely different options, all of which fall beneath the DLSS umbrella. Right here’s a fast rundown:

In video games, you normally received’t see the particular DLSS model. Fortunately, this info is obtainable on the PC Gaming Wiki, and you should utilize slightly deductive reasoning to determine the model of DLSS a selected sport is utilizing. If the sport solely has Tremendous Decision or simply “DLSS,” it’s utilizing some model of DLSS 2. If Body Technology is obtainable and Ray Reconstruction is just not, 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 might have. All RTX graphics playing cards help DLSS Tremendous Decision and Nvidia Reflex. Solely RTX 40-series GPUs, nevertheless, help Body Technology and Ray Reconstruction, along with Tremendous Decision and Reflex. If a sport helps a characteristic like Body Technology and your graphics card doesn’t, you received’t have the ability to activate the characteristic in a sport. On the flip aspect, in case your graphics card helps a characteristic like Body Technology and the sport doesn’t, you received’t see the choice in any respect.

Let’s check out every of those options in slightly extra depth.

Tremendous Decision

That is the core of DLSS, and should you see a sport that simply lists “DLSS” as an alternative of one of many particular options, it’s referring to Tremendous Decision. Tremendous Decision improves sport efficiency by rendering your sport at a decrease decision after which utilizing AI to upscale it. For example, should you’re taking part in a sport on a 4K monitor, your graphics card might 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 sport to run at a better body fee, and preserves as a lot picture high quality as potential.

Tremendous Decision is available in quite a lot of completely different modes that decide completely different render resolutions. Right here’s how they breakdown:

The three core modes of DLSS are High quality, Balanced, and Efficiency. The Extremely Efficiency mode is non-obligatory, so chances are you’ll not see it in each DLSS sport. You’re protected with the core three modes. Naturally, Balanced seems higher than Efficiency, and High quality seems the most effective, however all three modes are usable. I’d strive them every out to see which one will get you to your efficiency goal, choosing the very best high quality mode potential to succeed in your goal body fee.

Your output decision — the decision in your show — influences efficiency and picture high quality fairly a bit. The efficiency advantages can be decrease at decrease output resolutions, and the picture high quality can be worse. At 4K, for instance, the Efficiency mode seems nice. At 1080p, it’s a lot worse, each by way of picture high quality and efficiency.

Body Technology

Body Technology is just out there 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 characteristic 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 seems 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 subsequent 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 straight away. The delay isn’t big — a handful of milliseconds — but it surely’s sufficient that Body Technology requires Nvidia Reflex (extra on that quickly).

There are occasions when Frame Generation is problematic, nevertheless. It doesn’t enhance your sport’s responsiveness; it simply makes your sport look smoother. Due to that, should you’re utilizing Body Technology to take a sport from 30 frames per second (fps) to 60 fps, it should nonetheless really feel such as you’re taking part in at 30 fps. This impact is minimized the upper your preliminary body fee 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 out there for RTX 40-series GPUs. It’s only available in two games on the time of writing, too — Alan Wake 2 and Cyberpunk 2077. Though I think extra video games will help Ray Reconstruction sooner or later, it received’t be a mainstay like Tremendous Decision and Body Technology.

Tremendous Decision and Body Technology are centered on enhancing efficiency, however Ray Reconstruction is concentrated on enhancing picture high quality. It’s an AI-powered denoiser for ray tracing. That’s lots of technical jargon, and there are lots of technical particulars to the characteristic, however in follow, Ray Reconstruction makes use of AI to make ray tracing results extra correct.

This doesn’t affect efficiency, no less than within the two video games the characteristic is obtainable in, and it may possibly truly enhance efficiency relying on the scene. Like Body Technology, Ray Reconstruction is a toggle; there aren’t a number of modes. Nonetheless, it might not be out there relying in your graphics settings. In Cyberpunk 2077, for instance, Ray Reconstruction is just out there 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 element 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, but it surely’s been swept up into DLSS with the introduction of Body Technology. Because of the further latency attributable to Body Technology, you’ll be able to solely use the characteristic with Reflex turned on. In almost each sport, turning on Body Technology will mechanically activate Reflex, and also you received’t have the choice to show Reflex off.

DLAA

DLAA stands for Deep Learning Anti-Aliasing, and it’s an choice 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 sport at a decrease decision, it runs your sport at native decision.

The AI-driven anti-aliasing inherent in DLSS Tremendous Decision is absolutely good — so good, in reality, that turning on DLAA will make your sport look higher than simply native decision. It’s an important choice 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 seems wonderful.

Tips on how to get essentially the most out of DLSS

DLSS is obtainable in a whole bunch of video games, and that record is just rising. When you’ve got 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 how you can get essentially the most out of the characteristic set.

Hold your decision in thoughts

As talked about, DLSS Tremendous Decision works greatest at a excessive output decision. It seems and performs greatest should 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 might have a decrease output decision, DLSS will render your sport at an excellent decrease inside decision. This will create a CPU bottleneck as you go right down to lower-quality modes. In follow, that might imply you’re utilizing a top quality mode that appears worse with out offering any efficiency profit.

Should you’re working at a low decision like 1080p, at all times begin on the High quality preset earlier than shifting down. In lots of instances, you’ll discover a small efficiency enchancment at Balanced and virtually none at Efficiency.

Picture high quality can be an element at decrease resolutions, akin 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 fee

Should you’re utilizing DLSS Body Technology, you have to begin with a excessive base body fee. I like to recommend getting your sport working at 60 fps no less than by 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 fee in PC video games, however the primary purpose you need a excessive body fee is best responsiveness. Body Technology does nothing to enhance responsiveness, and resulting from how the expertise works, it may possibly truly make responsiveness barely worse by itself.

Body Technology works greatest on high of a excessive base body fee, pushing one thing from 60 fps to, for instance, 100 fps. You shouldn’t apply it to its personal in most conditions.

Typically DLSS seems higher

Chances are you’ll not want to make use of DLSS in much less demanding titles, even when they help the characteristic. There are positively instances the place DLSS could make a sport look higher. That’s the concept behind DLAA within the first place — the AI-assisted anti-aliasing in DLSS seems implausible. In video games the place you’re already getting good efficiency, strive turning on DLSS to High quality mode and see the way it seems.

It’s potential, 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 usually higher than TAA in video games, so higher-quality modes at greater resolutions can look higher with DLSS on.

Going past DLSS

Should you weren’t conscious, DLSS is open supply now, and it’s sprung a slightly sturdy group of modders hacking and altering the characteristic in video games. One of the vital highly effective instruments out there is DLSSTweaks, which is a free, open-source mission that may add further DLSS options to video games and alter the model.

What DLSSTweaks is absolutely good at is setting customized scaling. DLSS Tremendous Decision has a number of fastened scaling ratios by the presets. DLSSTweaks means that you can 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, akin to Lies of P, Pink Useless Redemption 2, and Atomic Coronary heart. 

DLSSTweaks carries a few caveats. The primary is that it doesn’t work with each sport. The GitHub web page maintains a list of titles that work, however you continue to might run into points. Moreover, because you’re modifying sport information, you shouldn’t use DLSSTweaks in on-line video games.

Most significantly, DLSSTweaks can not add DLSS options that aren’t in a sport. Newer variations of DLSS might have a barely higher high quality of efficiency, but when a sport doesn’t help Body Technology, for instance, DLSSTweaks can’t add it.

There are mods that add Body Technology into video games. Essentially 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 out there, as effectively. Some video games have free DLSS Body Technology mods, whereas others come by 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 characteristic, the time period has grown to embody a far better record of options. Most fashionable video games will help some mixture of DLSS options, and should you personal an RTX GPU, you must in all probability benefit from them — that’s one of many main reasons to buy an Nvidia graphics card, in any case.
