AMD FSR 3 FidelityFX Super Resolution Technology Unveiled at GDC 2023

AMD issued briefing material earlier this month, teasing an upcoming reveal of its next generation FidelityFX at GDC 2023. True to form, today the hardware specialist has announced that FidelityFX Super Resolution 3.0 is incoming. The company is playing catch up with rival NVIDIA, who have already issued version 3.0 of its DLSS graphics enhancer/upscaler for a small number of games. AMD says that FSR 3.0 is in an early stage of development, but it is hoped that its work on temporal upscaling will result in a number of improvements over the previous generation.

The engineering team is aiming for a 2x frame performance improvement over the existing FSR 2.0 technique, which it claims is already capable of: "computing more pixels than we have samples in the current frame." This will be achieved by generating a greater number of pixels in a current frame, via the addition of interpolated frames. It is highly likely that the team will reach a point in development where one sample, at least, will be created for every interpolated pixel. The team wants to prevent feedback loops from occurring - an interpolated frame will only be shown once, and any interpolation artifact would only remain for one frame.
However, a number of potential setbacks were noted - a reliance on color clamping to correct color of outdated samples is not entirely feasible. It will be difficult to produce non linear motion interpolation on 2D screen space motion vectors, and the interpolation of final frames will mean that all post-processing needs to be interpolated, also counting the user interface in the foreground. One of AMD's diagrams shows how a native rendering technique stacks up to FSR 2.0 and 3.0.
FSR 3.0 will enable a smoother overall gaming experience, and simultaneously this allows developers to focus more GPU time on visual quality. Latency reduction is a key focus area for FSR 3.0 - AMD has the gamer in mind, with high frame rates and the lowest achievable latency as basic requirements. The engineers are also aiming for a smooth upgrade path from titles that currently utilize version 2.0 of FSR.

Suit yourself. The 3070ti at 100 fps had lower latency (by 50%!!) than the 6700xt at 200 fps. That's absolutely insane
That article compares the performance of anti-lag and Reflux, not baseline latency of both brands. For that you'd need to have the same settings on both systems, which is impossible if both systems have different settings enabled. It's akin to me saying Nvidia has higher latency because with DLSS 3.0 FG enabled their latency is vastly worse than an AMD GPU at the same frame-rate. It's a conclusion by either a troll or someone ignorant of what they are looking at.

The article demonstrates the increase in lag when the GPU is fully utilized (100%), hence the difference is gone or reduced when CPU bound and we are simply left with the GPUs with the highest FPS scoring the lowest latency:

If AMD has some across the board latency penalty as you mislead earlier, it would have manifested here. Instead what we have is the AMD card with a lower latency.

The same Nvidia reflex latency reduction can be had, whether you use an AMD or Nvidia card, by capping your FPS to just below what your GPU can handle, assuming of course you are even hitting a GPU bottleneck. In a GPU bottlenecked scenario Anti-lag and Reflex max no difference in the latency, proving all the more how nonsensical your out of content mention of Igor's article is.

What? You got it completely wrong. Latency is important when you are gpu bound, so in higher resolutions, cause that's when you'll actually use FG. Nvidia cards have much lower latency when gpu bound, the test absolutely without any doubt proves it. I know you are a fan of amd and try to show otherwise but the reviewer himself completely agrees with me, so no point arguing about it.

3070ti at 4k has lower latency than the 6700xt at 1080p. Enough said, move on

Again, that article compares the performance of anti-lag and Reflux, not baseline latency of both brands.

Saying that Nvidia has lower latency in an Apples to Apple's comparison, for the reasons explained prior, it outright false.

And since reflex is used by nvidia and antilag by amd, nvidia cards have lower latency than amd cards. Even with FG probably judging by the numbers. So what is the issue here?

Because you don't understand the fact that 1) Having different settings enabled isn't apples to apples 2) latency reduction is only in certain GPU limited scenarios 3) Anyone can get the same effect by enabling an FPS cap. 4) Reflex is available in less than 1% of all games, making capping the FPS far more practical and providing the same benefits.

No you don't understand that we were specifically talking about FG. You said that it's horrible cause of the latency. ALL games that have FG also include reflex, therefore latency should be around the same levels as an amd card even with FG on. Stop it, just stop it man. You are wrong, it's fine. No biggie

Also since you keep mentioning fps cap, no, just no. You are not getting the same fps in every game or even in every area of the same game, how are you going to cap your framerate exactly?

Frame Generation requires reflex be enabled because the latency is crap. Nvidia themselves admit this by making that a requirement. Enabling reflex + Frame generation is going to net you worse latency vs a similar performing AMD card with an FPS cap set at just below the maximum FPS. Same applies to any Nvidia card as well.

As I've pointed out 3 times, Reflex achieves the same result as capping your FPS. And again, this only applies in games that are actually GPU bound.

Oh my god, how are you going to cap your fps? Are you going to change the fps cap on every single game you are playing? On every single area of every single game? Whatever man, didnt expect you to admit the obvious when amd is involved. Good day
