One thing I've just noticed is that the frame rate disclosed by glxgears is extremely slow.
glxgears 79 frames in 5.1 seconds = 15.565 FPS 86 frames in 5.0 seconds = 17.183 FPS 69 frames in 5.0 seconds = 13.754 FPS 101 frames in 5.0 seconds = 20.171 FPS 102 frames in 5.0 seconds = 20.217 FPS 102 frames in 5.0 seconds = 20.255 FPS In the past using earlier versions of ubuntu with the older driver, I've had much better frame rates, admittedly not in the 1,000's of FPS (it is an 8 year old graphics card), but (from memory) in the region of 750+FPS . I've attached xorg.0.log in the hope that somebody can suggest a solution to improve the FPS.
