Not enough to bother calling mother over: [root@coyote root]# glxgears 1516 frames in 5.0 seconds = 303.200 FPS 983 frames in 5.0 seconds = 196.600 FPS 832 frames in 5.0 seconds = 166.400 FPS 703 frames in 5.0 seconds = 140.600 FPS 663 frames in 5.0 seconds = 132.600 FPS 623 frames in 5.0 seconds = 124.600 FPS 585 frames in 5.0 seconds = 117.000 FPS 553 frames in 5.0 seconds = 110.600 FPS 554 frames in 5.0 seconds = 110.800 FPS 554 frames in 5.0 seconds = 110.800 FPS 554 frames in 5.0 seconds = 110.800 FPS 554 frames in 5.0 seconds = 110.800 FPS 514 frames in 5.0 seconds = 102.800 FPS 499 frames in 5.0 seconds = 99.800 FPS 499 frames in 5.0 seconds = 99.800 FPS 499 frames in 5.0 seconds = 99.800 FPS 499 frames in 5.0 seconds = 99.800 FPS 498 frames in 5.0 seconds = 99.600 FPS 499 frames in 5.0 seconds = 99.800 FPS 496 frames in 5.0 seconds = 99.200 FPS Broken pipe Its not using any cpu unless you count once or twice I saw it report .25%.
