CSMT stutter issues.

Post by toidi »

Hi folks, quick question that has me stumped and I have searched far and wide without any luck.
When I run ANY game in wine 3.3+ I have this strange issue where after a couple of minutes I will get severe FPS bottleneck for a few seconds every minute or so whenever csmt is enabled.

This happens on all builds, even with PBA/DXVK patches and compiled from source as well. I have tried various configurations of on/off of csmt and strictdrawordering to no avail.

TOP also doesn't highlight any surges or anything out of the ordinary when these stutters happen.
Mesa 18.0 and 18.1git make no difference.
Kernel options between RADEON and AMDGPU have no effect either.
I have also pretty much eliminated the chance it is being caused by heat issues.

I really am at a loss as to what is causing the problem and any tips or ideas would be very much appreciated.

Specs:
AMD 8350, R280X GCN1.1 card, 16gb 1866 mem. Arch with cinnamon DE (clean install).

Thanks in advance,

Danny
