Check your dmesg, if you find NVRM Xid errors, you might also notice Xorg is pegging the CPU, I get this all the time with the latest beta driver and I have to restart X, and sometimes even reboot, to fix the issue.

I'm not doing anything special in this moment, but my Xorg process won't go below 20% now is on 26%, I think there's something wrong, I'm running an Intel Core 2 Duo E8400, with a 9500GT and latest beta driver installed.
Compiz and latest kde4.
How can I optimize this?
