Is this performance reduction due to using the Microsoft implementation of OpenGL?
AFAIK, the stock .DLLs included with Microsoft operating systems provide a
software-only version, i.e. they do not take advantage of features nor of
the power available in modern graphics cards relying instead on the main
CPU. (I may be misinformed on this.)
Or are you saying that XP's grapical smoothing functions affect ALL graphic
output?
Just curious.

It's not suppoesed to affect but it does, affect. And the oeverall system
perfomance is affected accordingly, which is very noticable on slow
machines.
