Do note that neither ASYNC (which this dxvk repo does not support) nor GPL touches anything to do with general performance outside of shader compilation.

Yes i know but GTA V general performance is tied with the state cache as all three methods start equalizing when the state cache builds up

But los santos takes a long time to do that and I'm an annoying brat who wants it no stutter now! :P

https://gitlab.com/Ph42oN/dxvk-gplasync/ if you prefer to continue using async.

Oh well it is for me :P

No, it's not.

Also should i try this?

GTA V is a CPU bound/heavy game. What CPU does your system have?

Try frame capping it to 60 (or even lower, e.g. 45) using the environment variable DXVK_FRAME_RATE (or via config).

If that resolves the stutters completely, you need a better CPU to be able to push higher frame rates. (and Rockstar Games needs to find better programmers).

Also disable MSAA and other AA, only enable FXAA.

The AA implementation in the game is notoriously heavy on the GPU, where as FXAA is highly optimized.

Shadows to Soft.

You can download latest master from the CI here https://github.com/doitsujin/dxvk/actions/runs/4609600345
The newly released GE-Proton-7-54 already has it included along with Proton Experimental on steam

Oh someone explained why my general performance sucked until the shader cache was richer

The Game is heavly CPU bound as you said

And my puny i5-4750s was busy compiling shaders and when it's not performance is good

Hope the above change makes it work better for you in general 🙂

Running the game here on a low-end quad core (no SMT) Skylake Xeon and RX 580.

With GPL enabled (via RADV_PERFTEST=gpl) and frame cap to 45, there's no stuttering and frametime graph is flat. Even without prewarmed cache.

Make sure to remove mesa shader cache and dxvk state cache files when running different versions of Mesa and DXVK.

Upgrading to a more powerful processor, like the Zen 3 based Ryzen 5 5600 is another option to reach 60+ FPS without heavy frametime variance.

Hope the above change makes it work better for you in general 🙂

Ok that dxvk async you gave me completely removed stutter

And that config upped general performance

So all good now

Cool. Enjoy the game!
