For the past month I have been trying to figure this issue out to no avail. When the new xorg-server went stable a little over a month ago there were several posts related to opengl performance on the intel graphics cards none of which I was able to pull any information from. Prior to the upgrade, while running xorg-server 1.3 and intel video driver 2.1, I was able to run gnome with compiz-fusion (no flames on gnome please) without issue, and glxgears (yes I know that its not a benchmarking tool but it will illustrate the point just fine here) ran at about 700 fps. After the upgrade which included:
xf86-video-intel-2.7.1 mesa-7.4.2 xorg-server-1.5.3-r6 libdrm-2.4.11 My performance has dropped to the point where compiz-fusion no longer runs well on my computer. glxgears shows only 60 fps. Following some suggestions from earlier posts to the list I have tried upgrading my kernel and now run 2.6.28 with the i915 driver in the kernel selected. glxinfo shows: OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20090114 Anyone have any ideas that may help improve the performance on this card, FWIW the laptop is a Dell Inspiron E1405 with a GMA950 Intel chipset. Thanks, AJ
