thank you. I added this to my XF86Config, and now glxgears reports: 880 frames in 5.0 seconds = 176.000 FPS 878 frames in 5.0 seconds = 175.600 FPS 883 frames in 5.0 seconds = 176.600 FPS 880 frames in 5.0 seconds = 176.000 FPS 878 frames in 5.0 seconds = 175.600 FPS more than 50% better. However I ran into unexpected trouble building gltron and have been too busy/distracted to make it work it yet. If you know of a good open source opengl benchmark, I would be grateful to know about it. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
