A benchmark also measures specific hardware performance and tests optional features. glxgears only tests clear speed and the rate at which a modest-sized vertex buffer can be rendered. A useful sanity test, but nothing more. ~ C. _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
