IMHO, since the 'video/graphics' card is 'shared' by both OSes, it would.
Also, all 'updated drivers' for the Windows-partition usually come via Apple's Bootcamp updates.
BTW: I always thought that games looked better on the Windows-partition (running the same game on OS X and WinXP). But that may be purely 'subjective'...
