Compiz using GPU or CPU???


Hi,

I'm using the latest (3.4a) version of Sabayon Linux. It's great. The graphics and design are amazing. It comes pre-installed with loads of goodies. It uses NVIDIA binary drivers out of the box.

Anyways, the problem is that compiz runs slower/jerkier than with other distros. Effects get stuck midway (such as opening/closing windows). The OpenGL screensavers seem to run slower than normal. I tried re-installing the NVIDIA binary drivers manually, but no improvement. I have a GeForce 8500GT graphic card.

How can I be 100% sure my system is using the GPU to its fullest to render? Is it possible that rendering is taking place in software? My CPU is Core2Duo 6350. I see the NVIDIA Logo when X starts. My xorg.conf file looks like this (entries unrelated to graphics are not included):

Section "Module"

Load "dbe"
Load "i2c"
Load "glx"
Load "ddc"
Load "type1"
Load "freetype"
Load "extmod"
Load "synaptics"
Load "vbe"
# Load "dri"

You have a lot of options like Render Acceleration commented (#) out. Perhaps enabling some will give you better perfomance. Naturally make a copy of your xorg.conf before doing any changes, just in case things go wrong.
