The cpu was set for "ondemand", and was currently on 2.0Ghz. I now changed to "performance" and the cpu is always on 2.67Ghz. On the first qvdpautest after i changed this i got the same bad numbers as before. Tried several more times, but still bad numbers.
If i understand nvidia-settings correctly i only have one setting for PowerMizer, and that cant be changed?
Attribute 'GPUPerfModes' (tvdator:0.0): perf=0, nvclock=550, memclock=400
But i must say that i really appreciate all the help i'm getting. I really hope that i find what is wrong before everyone get tired of me =)
