Do frames win games? Not with DLSS 3

Digital Trends
“Frames win video games.” That’s been Nvidia’s advertising marketing campaign focused at esports gamers because the introduction of Nvidia Reflex. It’s an amazing slogan, catchy with the correct amount of reality, and the right pairing for Nvidia’s RTX applied sciences. In a brand new period of generated frames, although, it requires a little bit of context.
Nvidia’s DLSS 3 generates frames on RTX 40-series graphics playing cards, massively enhancing your efficiency. The trade-off, nevertheless, is a rise in latency, which hasn’t been an enormous deal up so far. In video games like Ratchet and Clank: Rift Apart and Cyberpunk 2077, you don’t want to fret about gaining a aggressive edge. But now, we’re seeing DLSS 3 for the primary time in a aggressive shooter: Call of Duty Modern Warfare 3. (*3*), the sport solely included DLSS 3 within the single-player marketing campaign, however after just a few days, it was patched into all recreation modes, together with Zombies and multiplayer.
I like seeing choices for players, so don’t misconstrue this column entry as me calling for DLSS 3 to be faraway from Modern Warfare 3. It’s an amazing software, and it ought to be within the recreation. But should you plan on competing within the recreation at a excessive degree, it is advisable to know in regards to the trade-off you’re making by producing frames. That will solely develop into extra vital if we begin seeing DLSS 3 in extra aggressive titles.

How do frames win video games?
We want to speak in regards to the concept behind frames profitable video games within the first place as a result of Nvidia has a degree with its advertising slogan. Your body price is only a illustration of latency between every body. If you’re working at 60 frames per second (fps), there’s 16.6ms between every body. If you double that to 120 fps, you half the latency down to eight.3ms. With a better body price, you see extra data sooner, permitting you to react faster in a aggressive setting.
This isn’t some high-level theoretical benefit, both. I noticed that firsthand in Nvidia’s system latency problem within the Kovaak’s goal coach simply how vital latency is. LTT ran a check with skilled esports gamers at totally different body charges, too, displaying that the most effective gamers hit their pictures extra typically with a better body price. Higher body charges gained’t make you a greater participant, however they’ll be sure that an amazing participant is acting at their finest.
That’s the advantage of extra frames. But the true benefit is general decrease latency. There’s some latency between frames, however the latency throughout your total PC will be far more vital. This breaks down into two areas. There’s whole system latency, which is the entire time is takes from whenever you carry out an motion (like clicking your mouse) to when the ultimate end result reveals up on-screen. There’s additionally PC latency, which is the time from when your PC receives the enter to the time it sends out a body, ignoring latency out of your enter machine and your monitor.
Nvidia additionally focuses on PC latency with its Reflex characteristic. This finds optimizations inside your PC to make sure your parts are as quick as they are often. This doesn’t enhance body charges — that’s tied to what Nvidia would name render latency, the time between every body — however as a substitute finds optimizations between your parts to enhance general PC latency.
All of this vital to put out as a result of low latency is important within the context of a aggressive recreation, and instruments like Nvidia Reflex, coupled with a excessive body price guarantee, that your PC latency is as little as it may presumably be. DLSS 3 Frame Generation, although, simply throws a wrench into that plan.
When frames don’t win video games

I examined Modern Warfare 3‘s multiplayer with two GPUs. One was my private rig with an RTX 4090 and a 3,440 x 1,440 monitor, whereas the opposite was an RTX 4060 Ti with a 1080p show. In each instances, I saved the graphics preset to Extreme and enabled DLSS Quality mode for upscaling.
In each instances, Frame Generation offers a pretty big leap in efficiency. With the RTX 4090, it’s offering a 21% increase, and with the RTX 4060 Ti, we’re seeing an 18% improve. The recreation was already working at a excessive body price, however in an period the place 360Hz screens are widespread for aggressive gamers, these efficiency enhancements definitely aren’t insignificant. By the logic of “frames win video games,” turning on DLSS Frame Generation would offer you a aggressive edge since we’re seeing a better body price. So, why isn’t that the case?

If you prolong this graph out and have a look at the typical PC latency, in each instances, there’s practically double the latency with Frame Generation turned on, even if that we’re seeing a better body price. And once we have a look at Reflex turned on with out Frame Generation, the hole is even increased. Also take into account that Frame Generation forces Reflex on.
In a aggressive setting, it’s fairly clear that you simply wouldn’t wish to flip Frame Generation on. This common PC latency metric contains the render latency — that latency between frames your GPU is rendering — so the additional frames you’re seeing with Frame Generation don’t do a lot of something. The recreation seems to be smoother, however from a aggressive perspective the place you need the bottom potential latency, these further frames gained’t aid you win the sport.
What’s happening?
So, if Frame Generation is supplying you with further frames, and further frames lower latency, why are we seeing a rise with the characteristic turned on in Modern Warfare 3? Well, it comes all the way down to how Frame Generation works, the overhead that it requires, and the truth that the frames you’re seeing aren’t all truly actual.
Let’s begin with how Frame Generation works. If you’re acquainted with DLSS 3 or AMD’s FSR 3, you’ll know that these options insert a generated body between every rendered body. The method these options get the data to generate the body is the place latency is launched. The options have a look at two rendered frames in sequence and use the information to estimate what a body in-between them would seem like.
In follow, your graphics card renders two frames. They’re carried out. You see the primary body, however earlier than you see the second, the method of producing the factitious body has to complete, and that body must be exhibited to you. The finish result’s that you simply’re seeing the second rendered body later than you usually would, creating further latency. The solely case the place there wouldn’t be further latency can be if DLSS Frame Generation actually doubled your body price with none overhead. And even then, that’s simply to attain the identical latency as you’d have with Frame Generation turned on.
The tough half about Frame Generation is that it hides the overhead it requires to work. If we take the earlier outcomes with the RTX 4060 Ti, we’re seeing 147 fps at 1080p. Those are all actual, rendered frames. With Frame Generation, each different body is generated, so we are able to minimize that last quantity in half. With Frame Generation turned on, your graphics card is barely rendering about 87 fps. That hole, between 147 fps and 87 fps, is a illustration of the overhead Frame Generation requires.
It’s fascinating to level out, however that overhead doesn’t account for a lot within the overwhelming majority of video games DLSS 3 is accessible in. The undeniable fact that Nvidia is ready to ship such excessive enhancements in smoothness whereas protecting DLSS 3 video games feeling responsive is a marvel. In Modern Warfare 3, nevertheless, you’ll wish to depart Frame Generation off should you plan on enjoying competitively.
Up so far, we haven’t seen the tech utilized in any fast-paced, aggressive setting. That could also be as a result of plenty of aggressive titles like Overwatch 2, Valorant, and League of Legends aren’t too demanding. We are seeing some next-gen titles with a aggressive angle, although, and I think about the latency points we’re seeing in Modern Warfare 3 will apply there, too.
A main instance is the upcoming The Finals, which is meant to launch in December. The recreation options ray tracing and DLSS 3, and it positively has a aggressive angle. Once once more, I admire the choice for players who don’t wish to sweat it out to be the perfect. But for these trying to climb their method up the ranks in aggressive video games, it is best to depart DLSS 3 turned off.
