Binary package hint: compiz
glxgears shows the following fps on my Nvidia 8600GT card when compiz is running:
173.14.12 driver:
Hardy, 32 bit: 4900 fps
Hardy, 64 bit: 5000 fps
Intrepid, 32 bit: 4200 fps
177.80 driver:
Intrepid, 32 bit: 3000 fps
ie there is a massive 40% in performance between Hardy using the old and Intrepid using the new driver and a 15% drop if both use the old driver.
With compiz disabled, all combinations of O/S and driver show around 5800 fps.
So with the new 177.80 driver, compiz is reducing glxgear performance by close to 50%.
