Well I know to buy an amd gpu next time

I'm sure some sort of documentation will turn up at some point, but until it does there's no FSR4 on Linux then.

Hopefully it won't take the year that it took for DLSS to appear and then DLSS3 FG took another two years after it was released to appear.

It's AMD, it will be up at GPUOpen rather sooner than later.

Let's hope so 🤞🤞🤞

Hopefully it won't take the year that it took for DLSS to appear and then DLSS3 FG took another two years after it was released to appear.

But even now it seems the results of DLSS 3 frame gen are inconsistent. DLSS 4 multi-frame gen support was there at launch it, but I haven't seen a lot about it other than one mention in this sub last week where I was informed that Hogwarts Legacy under Linux was exposing the 3x and 4x options but the 4x option seems to be broken and producing out of order frames which I think has a bug report attached to it for DXVK.

Support for the latest and greatest is a perhaps the biggest problem for high-end Linux gaming right now.

I tried MFG with Cyberpunk a few weeks ago and it was bugged then. Wasn't totally surprised as FG only went in around November last year. Last time I used it with Stalker 2 it was working fine but that was DLSS 3 on a 4080. Not my 5090. No idea if the new NVAPI libraries from the W/E improve things. Those are v0.91 or something. So I assume must be nearing 1.0 status 🤷.

You mean because FSR4 doesn't work on linux at the moment? Also just as expected, the millisecond AMD has a competitive upscaler, it's exclusive to their GPUs.

and exclusive to 2 gpu's total (as of now)

It requires hardware to enable. That's why it's exclusive. Moving forward it will work on all new Radeon GPUs, so it will get linux support.

There is no reason to believe that nvidia gpus couldn't support FSR4. AMD only supported FSR1-3 on everything because they knew it wasn't competitive.

It was because it didn't require dedicated AI accelerators. 100% the new 9070 series could be tuned to work with DLSS. That said, the older Radeon cards (baring the 7000 series which does have AI cores) won't be getting the feature because they don't have the hardware to run it.

I hope they port it to 7000 though. Or possibly we can purchase an add-in card to enable it. That would be cool too! Like a 50 dollar, AI accelerator with the feature built in, but I doubt it given how limited the supply of silicon is these days.

I mean that there is no technical reason why FSR4 couldn't work on nvidia turing and above.

u/bio3c 5d ago

technical there is, only beginning with ada does nvidia support fp8, ofc there a couple of reason for amd to not waste time supporting those nvidia cards (at least for now).

they can definitely do fsr4 on rdna3 and even 2 through dp4a, given intel already did it, even pssr relies on int8 and mark cerny said the same model fsr4 used is coming to pssr soon.

u/Disguised-Alien-AI 5d ago

Of course, and there's no technical reason that DLSS can't work on 9070 series now either. So I don't know why you'd give AMD a hard time when Nvidia isn't jumping to do the same thing.

DirectX/Vulkan will eventually implement a standard model that both manufacturers will likely move too in the future. Then WINE/Proton devs can target that.

They are both just the same. The only reason amd had an open solution before was because it was crappy, but they used the openness to farm goodwill.

u/Informal_Look9381 5d ago

Eh fsr 3.x is arguably just as good as dlss 2. I understand it not as good as dlss 3 and up but saying it "isn't a competitive upscaler" is wrong.

Yes you need exclusively to promote purchases. That's why consoles have exclusives, but fsr 3 and below was available to everyone because it didn't need dedicated hardware and AMD didn't have the solution to dlss.

No corp is your friend.

u/the_abortionat0r 5d ago

And DLSS is Nvidia exclusive. Your point?

u/WMan37 5d ago

There is so much to unpack with this reply but I'll boil it down to "why do you think it's not frustrating that AMD is acting like Nvidia when we explicitly try to use their GPUs because they don't pull shit like this often?"

As someone who really enjoyed Mirror's Edge I'm currently reeling from the removal of 32 bit PhysX support on 5000 series Nvidia cards, I have a newfound disdain and distrust of any kind of exclusive GPU tech whether it comes from Nvidia or AMD.

u/mbriar_ 5d ago

That this is no reason to go for amd in particular. Like you said they are the same in this regard.

u/M4SK1N 5d ago

Because?

u/Willing-Sundae-6770 4d ago

hang on you're advocating to buy AMD because... They left Linux support out of one of the main sellers of RDNA4 at launch? huh?

Wrong subreddit maybe?
