Valve are asking for help testing "ACO", a new Mesa shader compiler for AMD graphics

Quoting: jensMy best guess would still be a Google Stadia alternative.
Since they also focus on VR heavily, it could be something else too. VR doesn't really fit well with Stadia-like use case.

Quoting: YoRHa-2BYou cannot multi-thread compilers without sacrificing performance of the generated code. It's just not possible.
That really very much depends on the use case, and how compiler is designed and what it actually does. I'm not sure about shaders use case, but if some stages of the compilation are independent, they can be parallelized in general. That's quite commonly used in compilers to make compilation itself faster.

Quoting: YoRHa-2BI've had access to this for several months now and it really is promising. Most of my games do see small improvements, enough to match native D3D11 performance in some cases.

And then there's Nier: Automata, which sees a massive improvement
Is the actual compiler multithreaded? I actually felt stronger stuttering when shaders were recompiled for the first time. Resulting fps is higher, but to reduce stuttering, shouldn't it spread CPU load better?

Quoting: KristianDo any AMD cards have any kind of ray tracing acceleration?
No dedicated hardware in the current models, AMD recommend using general GPU features for that. But they plan to add something [External Link] in their future cards (probably to due to pressure from Nvidia).

Quoting: MohandevirI'm willing to give AMD another try... In another brand. :)
I have very good experience with Sapphire.

Just run a small test for TW3. aco produces around +3 fps, that's approximately +3.6% improvement in my case. That is something.

Quoting: SalvatosNo one here is saying we don't want native games or don't appreciate those publishers, but the bigger the company, the more likely it is to disregard considerations other than profit, and it would be lunacy to expect all of them to operate on virtue and principle.
Sure, I don't expect the likes of EA to operate any different from how they do. That wasn't my point. My point is that it's not required for gaming companies to operate that way and be a successful business, and positive examples demonstrate it. But surely we can't expect everyone to behave like better, and more forward looking publishers who support Linux.

Did you read their post. They answer this question.

Opened a thread here to separate discussion of the announcement from the actual benchmarks: https://www.gamingonlinux.com/forum/topic/3954

Very promising. I'll test it and will post some benchmarks. May be there should be a dedicated thread on GOL forum just for that? Or should we post them in comments here?
