Not sure if this is helpful to you, but here is my experience:
I have an older/cheaper onboard nvidia in my mediacenter. It was hooked up
to a 1920x1200 TFT screen. compiz was terribly slow and play video's did
not work with some error message.
I tried both the nvidia drivers as well as the Open Source nv driver and
was disappointed, blamed the old/cheap nvidia and the high resolution as
the cause for not being able to use compiz.
Initially I also had problems with display-errors that were attributed to
a very simple fix described here:
I finally found that by increasing the video memory size in the BIOS from
32MB to 128MB (system was upgraded from 512MB to 1536MB) compiz worked
very fast and the video-overlay/XV problems were gone.
My advice would be:
- Use the nvidia driver (we have dkms-enabled packages in RPMforge)
- Look at the tips in the wiki for compiz
- Increase the Video memory size in the BIOS to at least 128MB
And let me add that last point to the wiki, so people can find it there.
