Using the link you posted I was able to get similar numbers on my
card, if you scroll down to the bottom of the page there where it
talks about driconf, and set up your drirc file you should be able to
apply these settings system wide. I am still have some issues with
compiz-fusion running smoothly I currently dont have the cube working
it lags very bad with that. I will do some more research into the
kernel bug and see if upgrading and re-enabling tiling fixes this
issue. Thanks for the link and pointing me in the right direction.
