Ubuntu 64-bit More Competitive Against Mac OS X

Switching to a 64-bit Linux environment increased the frame-rate in Urban Terror by less than 1 FPS. Again, however, the Mac OS X graphics stack is much more mature and stable than the Intel Linux graphics stack that just switched over to using the Graphics Execution Manager, kernel mode-setting, DRI2, and is getting ready to move to Gallium3D.

Urban Terror has no separate 64-bit build so there really is not much to be expected from the 64-bit move with this test.

The frame-rate stayed the same between Ubuntu 32-bit and 64-bit when running Urban Terror at 1280 x 1024.
