afaik glxgears now is vblank synced by default and someone even wrote its
not a benchmarking tool. You can disable vblank syncing with dri-conf. When
it comes to openarena, regnum-online, nexuiz without GLSL it preformes fine
and is pretty playable on GM965. Windows does not preform that much faster
and no tests were done to show real difference.
