[ubuntu] Intel 946GZ graphics slow performance

view full story

http://ubuntuforums.org – Hi, I've just installed Ubuntu 11.10 on a fairly old computer (1gb RAM, Intel Pentium Dual Core, Intel 946GZ on-board graphics). Running unity 2d is fairly snappy, but graphics seem slow in certain circumstances: 1. Certain games (hedgewars), FPS of only about 30 2. glxgears, FPS of only about 40 This is on full screen with 1920 x 1080 resolution, 60hz. I have checked that the intel driver is being used and glxinfo shows direct rendering is possible and that the intel drive is used for openGL. I am not sure whether the graphics capabilities are really this slow or whether there is somethin (Hardware)
