na dokładkę glxgears
1067 frames in 5.0 seconds = 213.400 FPS
1200 frames in 5.0 seconds = 240.000 FPS
1080 frames in 5.0 seconds = 216.000 FPS
1200 frames in 5.0 seconds = 240.000 FPS
1080 frames in 5.0 seconds = 216.000 FPS

ogólnie cienizna. Pod windosem jest znacznie szybciej. Na oko, bo nie 
znam/mam żadnego porównywalnego benchmarku. Chyba spróbuję quake2...

ogólnie maszynki są szkoleniowe i maja ciągnąć troszkę softwaru Tivoli 
pod linuksem + 2x instancja windos/vmware.  Są to celerony 2.8, 2GB ram. 
Powinny pociągnąć gdyby nie koszmarna grafa...
