Description Denis 2018-11-13 14:01:37 UTC

Hi.
I think that it is good to create a new issue so we will have possibility to track improvements on this.

I linked the original ticket, also below link to the renderdoc trace which reproduces issue:

So as soon as Jason and dxvk dev provides fixes, I will be able to test them within this bug.

With Steam Play 3.16-5 Beta with DXVK 0.93, the menu performance is pretty similar as with that Mesa branch tested before: around 20 FPS in videos and menus but it has some bugs it hadn't before.

The main menu keeps resetting: it loads correctly but then the screen become black, it loads again and the cycle at infinitum. It is possible to navigate on it, but it is pretty strange. I don't observe this using Steam Play 3.16-4 (but observe bad performance). Unfortunately, the main game is still an absolute disgrace running at 1 FPS.

We can definitely look into the 1FPS issue, but for the infinite loading loop, I think you should file a bug against Proton : https://github.com/ValveSoftware/Proton

I have upgraded Mesa to 19.0.0-devel (git-c6b37e5412) and Vulkan to 1.1.96 and I noticed constant messages on Steam logs:

INTEL-MESA: error: vulkan/anv_descriptor_set.c:530: VK_ERROR_OUT_OF_POOL_MEMORY

Around every 5 seconds this message appears. I did not notice performance changes on this game, but on DiRT 3 Complete Edition it started slower and with significant stutter (cache being built?), but then became better than the previous experiences.

About the menu issue, it was really a Proton regression.

Closing, the menu issue was coming from Proton.
