Quoting: Shmerl
Quoting: sr_ls_boySince we are discussing llvm, I'm looking for a way to add a suffix to the name of the targets.
For example, clang would be renamed clang-32. To do this with autotools you would add the
option, --program-suffix=-32. But I haven't figured out how to do this with cmake.

Why do you need clang though? For Mesa you only need libllvm.

Quoting: chancho_zombieoff-topic, but anyone tried AMDVLK from github recently?? with the latest pull I got a 5 fps increment in Shadow of the TR which is a lot considering the total average fps is 45

I haven't used it in a while, since radv became very good. But I can try building it again and compare with aco.

I've tested other games and it's only in Shadow of the Tomb Raider that I'm noticing that increment. Anyway it would be interesting to know if it happens for you as well, you can download the Shadow of the TR demo and test with that.

Interesting results. Using aco, vs Mesa master vs latest amdvlk in TW3 with dxvk master, aco was actually behind this time, but slightly.

radv/aco:


radv/llvm:


amdvlk:


That's just framerates, I didn't really analyze stutter.

Just tested Mesa-aco with Star Citizen (see the thread. It works, but the game crashes during quantum flight. Does it work for anyone?

How did you get Star Citizen? Did you pay for it with no contracts?

Just pledged for the starter Aurora package.

Quoting: GuestIt runs shamelessly brilliant now, I am totally intrigued. After the initial very low shader stutters, the game runs like a charm. FPS is still borked by the game itself, lacking optimization but that is for most windows users as well.

Is it just as slow in Windows?

that confirms what I suspected, there were some improvements in AMDVLK.

Yes, amdvlk has improved. but that's just for framerate, I didn't measure stutter levels vs radv/aco.

you guys should try AMDGPU pro driver 19.20, shaders compile so fast but some games has graphical bugs like unreal engine 4 games, its almost stutter free

Quoting: LinuxwarperMy small tests:

TALOS Principle: 75.6 - 76.4(ACO)
The Witcher 3: 77 - 82 (ACO)
PREY (demo) : 69 - 73 (ACO)

General note: Games stuttered alot without ACO when running for first time or when they had not been played for a while. To a point games would freeze a frame briefly. With ACO the stuttering was noticeably less to say the least.
