Description

I cleared the game on 04/2018. Tested the game today with a full up to date stack, after playing hardly a few secs, I get a system hang, video settings to lowest. All components are from git repos of last sunday:
linux (amd-staging-drm-next), drm, llvm, mesa-gl, mesa-vulkan, xserver, xf86-video-amdgpu.
Cannot even get any logs from the hang.
