glxspheres
Polygons in scene: 62464
Visual ID of window: 0x27
Context is Direct
OpenGL Renderer: GeForce GT 555M/PCIe/SSE2
1118.659279 frames/sec - 1248.423755 Mpixels/sec
1108.279496 frames/sec - 1236.839918 Mpixels/sec
1109.925904 frames/sec - 1238.677309 Mpixels/sec
1110.108420 frames/sec - 1238.880997 Mpixels/sec

This is what theoretically can be achieved (without vsync) if we do away
with VirtualGL.
