--- Comment #58 from Mauro Gaspari ilvipero@gmx.com --- After a long time without crashes on Tumbleweed, I wanted to prepare a test setup for valve mesa built with ACO. So I installed Ubuntu Budgie 18.04 LTS with hardware enablement stack and I noticed the OS freezes are now back, even on the RadeonVII.

What I noticed in the game behavior is this. This is a game running on crossover (wine) with DX11 and DXVK. I want to point out that I do alt-tab out of games to do other things, so this might be a factor to consider. But again, I do the same on my NVIDIA-GPU laptop and I never had a single freeze or fps drop. Not sure if point 2 and 3 are related, I just wanted to share my observations.

1. Game starts with excellent FPS. I can hear GPU fans spinning. 2. After a while, game loses a lot of FPS starts to become slow and sluggish, GPU seems to be no longer doing much and I can no longer hear the fans spinning. 3. After a while longer, the whole OS freezes as described in my first post.

What I am going to do next: 1. Use the workaround of comment #47 and test for a few days. 2. Install Valve mesa-aco with ubuntu PPA and test (without workarounds) for a few days.

I will report back when I have more details on my tests.
