FreeBSD: A Faster Platform For Linux Gaming Than Linux?
The performance story is similar with OpenArena, which is the least demanding OpenGL Linux benchmark used.
With OpenArena, the Ubuntu x86 performance was quicker to fall behind PC-BSD x86 than the x86_64 builds.
At 1920 x 1080, running the OpenArena Linux build on the BSD OS was about 14% faster than the latest Ubuntu Linux release. Worth noting is that for OpenArena, unlike some of these other tests, the 64-bit Linux build is faster than the 32-bit Linux build.
