There really is not any change in the Bullet Physics Engine performance between Fedora "Goddard" and Ubuntu "Lucid Lynx" when running on the one AMD and two Intel test systems.

The C-Ray performance is also close with it being heavily CPU limited in this multi-threaded ray-tracing benchmark.

There also is not much of a difference in the x264 video encoding performance between Fedora 13 and Ubuntu 10.04 LTS even though their compilers and kernel differ slightly.
