Intel OpenGL Performance: OS X vs. Windows vs. Linux
Yep, Mesa Git is regressed compared to the stable releases. This is unfortunate since this is one of the rare OpenGL games where the Intel Linux driver is competing with the Intel Windows driver. I've talked with the usual Intel OTC Linux graphics drivers this week at LinuxCon/GStreamer in San Diego, but unfortunately, they aren't aware of the Nexuiz regression, as their QA team didn't try it yet.
