Got my hands on counter-strike Global Offensive. I run an up-to-date fedora rawhide on x86_64 (3.20 kernel and mesa 10.5.0). I get a lot of rendering artifacts, GPU lock ups (rare, on ring 0 and 5), VM read faults from the TC block (texture cache I guess) for some VMs... The video settings are set to the minimum (in a 1920x1080 window) My GPU is a R9 280X (TAHITI XT).

Does it work better with current Mesa Git master? Specifically, this commit might help at least for the rendering artifacts: http://cgit.freedesktop.org/mesa/mesa/commit/?id=7692704b144b2aa9a57767a43212ceb5aad6638a
Sorry, cannot build easily mesa git on fedora rawhide for x86_64 and x86. Some dark kludge related to llvm blocked it (got some troubles with some "python mako" stuff too). I would need to build manually a near whole devel graphic stack on the side with all SDK dependencies. Have to wait for fedora to sort out their kludgy kludge llvm mess or pray for a fedora recent mesa update with the above patch. Leave that bug be. Once I have a reasonable way to test mesa git, I'll come back. (hope the fedora guys will provide a mesa update before me finishing my distro).
