Default Re: FX5200, Athlon 64, 9746, Twinview, running very slow

I have some more information that might be useful;

Running glxgears sometimes results in smooth operation for a few seconds and then it suddenly gets worse (slow to respond to keypresses, mouse input, etc.). glxgears -printfps shows;

Code:
andy@terrapin:~$ glxgears -printfps
2881 frames in 5.0 seconds = 576.181 FPS
2933 frames in 5.0 seconds = 586.446 FPS
andy@terrapin:~$ glxgears -printfps
805 frames in 5.1 seconds = 157.202 FPS
26 frames in 5.2 seconds =  5.032 FPS
27 frames in 5.0 seconds =  5.377 FPS
27 frames in 5.2 seconds =  5.218 FPS
33 frames in 5.0 seconds =  6.564 FPS
26 frames in 5.0 seconds =  5.184 FPS
26 frames in 5.0 seconds =  5.183 FPS
Also, if I run top in another window whilst running glxgears, I can see that X takes up 100% of a CPU, the glxgears process about 60% of a cpu. Around 45% of a cpu is taken up serving software interrupts! (surely that can't be right for something as simple as glxgears!).

Cheers,

Andrew
