Comment # 13 on bug 92923 from pat

2048M VRAM

Test 1:
Version:  OpenGL 3.0 [3.0 Mesa 11.2.0-devel (git-6f898f7)]
Patched with both patches you provided.

With patch: the graph spikes up to 45.5 MB during the loading screen, later it
stays at 0 byte. When I turn around it goes up to KB but not MB. Still around 3
FPS, up to 11 when looking at the sky.
