When ending out this initial NVIDIA FreeBSD 9.1 benchmarking with Xonotic, the results were rather intriguing. Namely for the GeForce GTX 680 "Kepler" (but for certain cases also with the other NVIDIA GPUs), the PC-BSD 9.1 performance was faster than Ubuntu Linux and Windows 8. This is rather interesting given that FreeBSD is using its Linux emulation layer for binary compatibility. Accounting for part of the performance difference may be the NVIDIA 310.44 driver in FreeBSD Ports over the 325 Beta, PC-BSD using KDE by default (though other Phoronix tests have shown Ubuntu's Unity/Compiz no longer implies a performance penalty), or the 32-bit binaries that are used due to the FreeBSD Linux limitations, but regardless even in the other tests FreeBSD/PC-BSD 9.1 had a very strong performance showing against Ubuntu 13.10 and Windows 8.
