Radeon RX 7800 XT and RX 7700 XT revealed, plus more details on FSR 3

By - | Views: 40,767

AMD just announced the Radeon RX 7800 XT and Radeon RX 7700 XT Graphics Cards, and they're giving out more details on FidelityFX Super Resolution 3 (FSR 3).

Of course availability is the big question. AMD said to expect them both on September 6th from partners including ASRock, ASUS, Biostar, Gigabyte, PowerColor, Sapphire, Vastarmor, XFX and Yeston. Plus they will be selecting them direct on the same date.

Here's the specs sheets AMD gave out:

As for FidelityFX Super Resolution 3 (FSR 3), AMD have a new blog post up with even more details. The first titles to get it will be Forspoken and Immortals of Aveum some time in "early fall". With other titles confirmed to be adding it later including Cyberpunk 2077, Space Marine 2, Frostpunk 2, Squad, Starship Troopers Extermination, Avatar Frontiers of Pandora, Alters, Crimson Desert, Like a Dragon Infinite Wealth and Black Myth Wukong.

The key addition in FSR3 is frame generation that AMD say "uses an enhanced version of AMD Fluid Motion Frames (AFMF) optical flow technology and temporal game data such as motion vectors to generate additional high-quality frames for a higher framerate in supported games, up to 2x2". Useful for games that you want to bump up to 4K with Ray Tracing.

One thing they've address is ensuring it doesn't impact the UI of a game, so they include "UI processing included as an integral part of our solution to minimize any impact frame generation may have on the in-game interface" and FSR3 also includes the latest version of their temporal upscaling that's integrated with the new frame generation.

Another addition in FSR 3 is a "Native AA" quality mode that allows you to use FSR 3 without applying any upscaling but still gives you the high-quality anti-aliasing and sharpening of FSR. It will come with a performance cost though, but might look better than what AA some games provide out of the box.

AMD has also committed to keeping it open source and will be added to the AMD FidelityFX SDK.

Oh, that's what I was waiting for. It was weird they always conflated temporal anti-aliasing with upscaling before. They totally don't need to be.

May be they can turn FSR without upscaling part into a Vulkan layer now, similar to how VkBasalt does it. Otherwise there is no easy way to use it.

I'm currently using VkBasalt SMAA with Deus Ex: Mankind Divided (Wine+vkd3d-proton) and it works pretty well and better than game's own AA options.

Just out of curiosity, what prevents Valve from upgrading Gamescope's integrated FSR with FSR2.2 or FSR3?

Reminds of when I played Grimrock 2, the jaggies were horrible until I learned about basalt

For some reason game's anti-aliasing has very bad performance, framerate is tanked completely. And their temporal AA option is worse. VkBasalt SMAA works with good performance in comparison.

I don't think that would work considering FSR 2/3 needs access to motion vectors, depth buffer and a ton of other data from the game to work properly. It's possible in theory by having the layer read that data from the game process but that would likely require per-game support.

for some reason i can't get excited about those graphs. Sure new games on ultra high @4k with raytracing are going to be demanding. But i can't shake the feeling that an uber expensive brand new high TDP 7900XTX with TFLOPs to space and back should be able to run these current games around 60FPS without FSR3.

will FS3 be used to justify even more shitty optimisation of AAA titles ?


Honestly AAA gaming is pretty much dead to me right now, it's not the Size of the games, the lacklustre optimisation, the exorbitant pricing models on unfinished releases with DLC being used as a patch, or the not actually owning it, or even the DRM anti-cheat spyware.. let alone the way these companies treat their staff. It's actually because most (not all) of these games frankly suck.

That said, im really enjoying Indie / AA and retro games a heck of a lot more TBH and i dont need FS3 for that.

Hmm, who is doing these charts!? Performance Mode is slower than Quality Mode? And on the legend in the next chart there are two items with the same color.

I think FSR 2/3 needs to be support by the game, because it uses temporal data, which FSR 1 does not.

Amusing that they benchmarked Forspoken, a game which most reviewers said was horrible :P
