FSR4 running on RDNA3 in Linux via hack.

[Hecate91]

There are videos from the biggest Youtubers confirming what we have known about Nvidia for years.

GN,Paul's Hardware, Der8auer, as well as Jaytwocents have videos, I may be missing other channels discussing it, but Nvidia has been lying and screwing reviewers and customers for years. And it has only gotten so bad recently that everyone is talking about Nvidia's tactics. I don't understand how anyone in good faith could praise Nvidia for their trying to control reviews, with a lack of caring about the consumer market to the point of launching bad drivers and not fixing a dangerous power connector.

They'll take every chance possible to bash on AMD while tiptoeing around actually criticizing Nvidia, it's all roses and sugar when it comes to team green. It isn't worth the argument with someone when they keep voting with their wallet to support the jacket man like they have some agenda in supporting a company even though said company doesn't care about the gaming market.
I think calling AMD software sewage is an interesting take while the multi trillion dollar company has repeatedly launched drivers causing crashing and all sorts of issues.

Ahem. I'm a he. Male, 31. And I don't "tip toe" around anything Nvidia, interesting choice of words, though.

it turns out that many, many things don't exactly smell of roses here at the green camp, either.

OK, what does this have to do with DLLs

You used the word sewage to describe AMD's software then accused them of being ignorant teens. This is not the only thread where you have waxed negatively on AMD. Look how you are talking about DLSS being some technical tour de force when Hyper RX works in every single Game.

And it's something I'm happy to stand by. Have I offended your feelings by speaking ill of your favorite graphics vendor? Oh, too bad. Let's skip the off topic banter, because we aren't changing each others' minds. In fact, I have no intention of changing yours, either.

Look guys, I'm obviously not a nvidia fanboy, buying AMD this gen was honestly a good move IMO given adas cost at the time. I love the hardware. But the software? I wouldn't call it sewage but it certainly could use some work in some departments and it does seem like they rush an underbaked product at times to compete. This is trying to be constructive, AMD can survive without the internets defense. You aren't really helping here.

I agree, you're being both fair and reasonable. And I'm not even calling the feature that, FSR 4 is pretty cool and honestly impressive tech, considered it's their first generation ML-based upscaler. Just the programming practice of injecting DLLs willy nilly with no proper framework or API provided. I don't agree with that. 5 minutes playing around with a Bethesda game with a script extender loaded should be a masterclass of learning first hand how finicky DLLs can be.

This has long since devolved into feelings and ad hominems, so idk I guess I'll just unsub. I can be easily reached for any further discourse anyway. Cheers

Again, you are right, but a bethesda game is probably not the best stability example for ANYTHING. But yes solid concept otherwise, heh.

What Dr.Dro forgets is that the 7900 series are that fast that you do need need to use FSR. This is obvious with how much effort he has taken into defending his position. Meanwhile I tried Total Conflict Resistance and as usual everything was set to Epic I turned off Vsync and 100+ FPS at 4K. It is what the fan boys forget that native is still fine for PC gaming

Lol, this made me chuckle. How is this relevant to what dr dro has been saying?

Hi guys, any news about it?

No. AMD has made it clear that there are no plans to backport FSR 4 to earlier generation GPUs at this time. The Linux method is unofficial, unwieldy and something if you've gotta ask about, it's not for you.

Buy nvidia, problem solved

getting FSR4 to work on older gpu probably was more of a proof of concept that it can work though very inefficiently. It shown it can work but not likely gonna happen as its very slow.

@arbiter
Proof of concept and potentially Valve might have wanted go see whether it would be viable to try running on the Deck. It doesn’t seem worth it, but the fact that the hack itself exists and is… workable is interesting by itself.

Someone did same thing with ray tracing on old GTX 1000 series cards 6 years ago, Yes it works but same results of stupid slow slideshow.

GTX 10 series supports software RT through driver (on 1070 and up). AMD refused to implement this in their Windows driver. Someone figured how to do it on Linux, too, using the open source stack.

Someone seems to have been able to activate FSR4 in RDNA 3 with an apparently simple method, but it still seems suspicious to me.

Copy-pasting here:

"Very simple, actually. New version of mesa on linux (you can think about it like a part of a AMD driver in that case) includes a patch for FP16 emulating, via FP8 for RDNA3. To use it simply install mesa 25.2 and add to game launch option in steam: DXIL_SPIRV_CONFIG=wmma_rdna3_workaround

Another thing that you need is to enable FSR4, for that you will either need to use dll injection tool like optiscaler or simply put parsed amdxcffx64.dll from amd windows driver to system32 folder of game prefix. Use optiscaler.

And finally, you need Proton (translation layer, that runs windows games on linux) with FSR4 patch. You can either use proton-ge or proton-cachyos. To enable FSR4 trick: FSR4_UPGRADE=1

If I recall correctly, new stable release of mesa planned for august. After that those patches will be in any linux distro out of the box. IF amd won't play a trick on us and ask to remove that feature."

I'll try or maybe I'll wait for August for the new mesa.
