Paul, is the game play smooth (fluid motion) or is there somesort it twitching?

edit: Hmmm... maybe the TimeGetDevCaps() returns so 'big' time resolution for some reason that no faster timing isn't possible.

My second doubt is that compatible bitmap is not so comptible because of those two display adapters. So, GDI converts it's format on every blit and that's why the framerate drops.... perhaps.

Very strange indeed...
