It feels like it's faster, but Youtube is still slow and jumpy.

Jep, even though I check using htop(1) bevor I start X.
Red bar at 100% for CPU 0, but there is process consuming more than 0.1% CPU
time.

You might be right, 12000 seems a bit too much.

Here is my "Device" section:
Section "Device"
### Available Driver options are:-
### Values: : integer, : float, : "True"/"False",
### : "String", : " Hz/kHz/MHz",
### : "%"
### [arg]: arg optional
#Option "SWcursor" # []
#Option "kmsdev"#
#Option "ShadowFB" # []
#Option "AccelMethod" #
#Option "PageFlip" # []
#Option "ZaphodHeads" #
#Option "DoubleShadow" # []
#Option "Atomic"# []
Identifier "Card0"
Driver "modesetting"
BusID "PCI:0:2:0"
EndSection
I changed the Driver to "intel".
But I don't realy see any difference.
