Hi,
I know glxgears is not a benchmark, but this behaviour feels strange.
Running Ubuntu 8.10 and fglrx on a radeon hd 3430 and playing with cpu throttling modes, I get :
with powersave mode:
15623 frames in 5.0 seconds = 3124.463 FPS
15640 frames in 5.0 seconds = 3127.870 FPS
15625 frames in 5.0 seconds = 3124.844 FPS
cpu load is 16%
with performance mode:
4978 frames in 5.0 seconds = 995.586 FPS
5002 frames in 5.0 seconds = 1000.375 FPS
5001 frames in 5.0 seconds = 1000.199 FPS
cpu load is 97%
so I get three times less performance using a supposedly powersaving mode. Does anybody know why? It's not a problem, just curiosity though...
