Hi Rudolf, > I really hope you're not _that_ surprized! > Unless I am very much mistaken, I already warned (in general) for 8/32/ > 64 bit accesses.. Ah, don't get me wrong. I was aware of it since I read in the stampTV code which must have been in 2001 or so. I just thought there would be a difference in writing too, even with MTRR enabled. I never really experimented with it that much. Now I'm still thinking about how to integrate this with the drawing modes of Painter, in a way that all this code duplication is removed too. Is there any particular speed penalty associated with using function pointers? I never used those on purpose before. Best regards, -Stephan
