When getting things going with the DarkPlaces-powered Nexuiz, even for this defunct open-source game the Windows 7 OpenGL performance is still superior. Upgrading to Mesa 9.2 boosts the Intel Ivy Bridge performance, but even then the Microsoft operating system with closed-source Intel driver is still 14% faster.

For the OpenArena games that aren't graphically demanding, the performance between Linux and Windows was close to the same.

The OpenArena frame latency as reported through its id Tech 3 (ioquake3) derived engine was close between Windows and Linux. The average frame latency for both Linux and Windows was under 30ms while the peak latency on Windows was 95ms and under Ubuntu 13.10 was 51ms or 76ms on the newer stack.
