Will FSR 3 frame generation work at all on Linux? (self.linux_gaming)

AMD announced FSR 3 will allow for fluid motion frame generation in-game on almost any GPU in any DirectX12 game, doubling or even tripling your FPS.

Would this work on Linux? Considering DirectX to Vulkan translation and our lack of Radeon software. Obviously I expect when FSR 3 releases it'll be a little while until people get it working on Linux if it is possible to get it to work.

I'm quite excited for FSR 3, not that I don't have a good GPU (I have a 6800XT) but I'm just excited to try real-time frame generation without spending a small fortune on a sub-par GPU from a sub-par company. Should I, and probably many other Linux gamers, look forward to FSR 3?

FSR2 works well on Linux, I think FSR3 will be supported fairly soon after Windows, thanks to the mesa driver.

Does it even require driver support? I was under the impression that FSR 2 only required the game to support it and provide inputs.

[–] H2207 2 points 1 year ago

Inputs to the driver probably.

I think it will work well considering that AMD is the provider of processor and GPU/apu of steam deck

[–] H2207 11 points 1 year ago

Yeah good point, I forgot about the Steamdeck. So AMD themselves will probably make an effort to get it working then.

I certainly hope so, it being one of the things that would actually improve the viability of Linux as a viable platform for gaming big time.

But seeing how we are just gonna see freesync support with kernel 6.5, I think definitely will take a long time.

[–] Molecular0079 7 points 1 year ago

Eh? Pretty sure freesync was already a thing before kernel 6.5.

[–] H2207 4 points 1 year ago

Well Freesync is probably a bit more complicated to implement than FSR 3 considering the scope, Freesync works in-games and in the desktop so I imagine the display server and compositor need to support it. To me FSR 3 seems nothing more than a driver update and a new version of wine / proton.

How's that different than VRR or TearFree which we already have?

[–] juipeltje 1 points 1 year ago

I'm confused by this as well.

[–] Presi300 2 points 1 year ago

Kernel 6.5 is gonna have freesync? Pog

[–] [email protected] 2 points 1 year ago (1 children)

FreeSync seems to work fine for me since switching to an AMD GPU. Does it not work for you?

[–] 0xb 1 points 1 year ago (1 children)

I think I read the changelog wrong because apparently freesync has been a thing in the kernel since a while back. Probably just some improvement being implemented in 6.5

To be honest I haven't ever tested because while my display technically supports it, it's a pretty basic display with not a lot or Hz range so I haven't bothered to check.

[–] [email protected] 2 points 1 year ago

I mostly notice because I have two displays with different refresh rates, so it's pretty noticable.
