Some quick testing of the Ubuntu Linux 3.2 kernels as available from the Ubuntu 12.04 LTS Precise repository for a future article on Phoronix.com that quickly looks at whether the OpenGL / gaming performance is affected by the Ubuntu Linux low-latency kernel flavor.

This is a test of OpenArena, a popular open-source first-person shooter. This game is based upon ioquake3, which in turn uses the GPL version of id Software's Quake 3 engine. Learn more via the OpenBenchmarking.org test page.
This is a benchmark of Nexuiz, a popular open-source first-person shooter. This game uses the DarkPlaces engine, which is a largely modified version of the Quake engine with extra features such as High Dynamic Range rendering and OpenGL 2.0 shaders.
