I am wondering how to quickly test performance of my 3D graphics. Since
glxgears is not benchmark what should I use. Also glxgears sometimes stuck at 60FPS, you cannot even compare before/after driver update (e.g. adding xorg-edgers PPA). Even glxgears doesn't really work out of box.
One possibility is screensavers, but you can't see FPS. I am also not willing to install 600MB nexuiz, specially if I am running on Live-CD. Other 3D games are also very big... Unigine tests are too demanding for opensource drivers (problems with too low OpenGL and probably texture compression (S3TC...)). I would also like to test OpenGL 2.x extentions.
How to quickly test your 3D performance?
