I am indeed using a VMWare. I should probably check the VirtualBox version? Or is there another fix that I could try? Would you expect a different FPS (from glxgear)?

Thank you very much for your time and patience.

Attached is the output of dmesg. I am not very familiar with evaluating the output of glxgear. Here is a sample of the frames per second that is printing:

7920 frames in 5.0 seconds = 1569.891 FPS 8280 frames in 5.0 seconds = 1654.312 FPS 7920 frames in 5.0 seconds = 1576.902 FPS 8520 frames in 5.0 seconds = 1688.239 FPS 9000 frames in 5.0 seconds = 1789.300 FPS 8520 frames in 5.1 seconds = 1683.927 FPS 8359 frames in 5.1 seconds = 1650.856 FPS 8280 frames in 5.0 seconds = 1653.440 FPS 8280 frames in 5.0 seconds = 1643.529 FPS 8040 frames in 5.0 seconds = 1599.484 FPS 9227 frames in 5.1 seconds = 1825.203 FPS 8760 frames in 5.1 seconds = 1732.738 FPS 8160 frames in 5.0 seconds = 1630.169 FPS 8400 frames in 5.0 seconds = 1677.716 FPS 8520 frames in 5.0 seconds = 1701.086 FPS 8021 frames in 5.1 seconds = 1587.792 FPS
