Even though there were reports that glthread improves performance in Witcher 2,
and it was enabled via drirc in recent mesa versions, it never worked for me.
"API-thread-offloaded-slots" always stays at zero, see attached screenshot.
In other games like Civilization 5 glthread works on my system as expected.
My current package versions:
linux-4.13.5
mesa-17.2.2
llvm-5.0.0
libdrm-2.4.82
xf86-video-amdgpu-1.4.0</pre>
