It makes almost zero difference with modern graphics cards (ATI/nVidia/3Dlabs).

All three major vendors have 'unified drivers' where 99% of the code is
identical for Linux and Windows.

Some operating system operations are faster on one OS versus the other - but
most 'realtime' applications do so little of that stuff that they aren't
likely to notice.
