> Kai, can you see if this is also the case for you?

Nope, works for me, as I reported in comment #45. In Unigine Heaven I get t
2560×1440 (Renderer: OpenGL, Mode: 2560x1440 8xAA fullscreen, Preset: Custom,
Quality: Ultra, Tessellation: disabled) an average of 20 FPS and the GPU and
memory is clocked to the maximum settings. At 1920×1080 (windowed, otherwise
the same as above) I get somewhere betwen 30 and 50 FPS, again the GPU and
memory is clocked to the maximum. I can trigger the reclocking (not to max)
even with
  vblan_mode=0 glxgears
I'm not saying, the results for Heaven shouldn't be better, because right now,
this is all without tesselation, since radeonsi doesn't have support for it
yet. And a low FPS value of 6 FPS is really bad. But then, there is still lots
of room for improvements from what I understand.

Unigine benchmark results:
FPS: 19.8
Score: 499
Min FPS: 6.3
Max FPS: 29.7

Btw, the benchmark/engine doesn't recognize the GPU and VRAM with radeonsi:
"GPU model: Unknown GPU (256MB) x1"
