Why do you need a refresh rate of "between 80 and 160" Hz? The screen will not refresh that frequently, so you wouldn't get anything more once you exceeded the refresh rate of the display.

After thinking about it a bit more, I realize now that it doesn't need to be that large but rather around half. 40-60 frames should be fine. I'm going for absolute fluidness, but thinking about what you said and realizing that the display will only be short lived made me realize that "fluidness" is relative.

Anyway, I guess I'm going with OpenGL, but while we're on the subject, I wonder how Apple does their genie effects. A) I wonder what the actual algorithm is that determines the transformation the image of the window makes, and B) I wonder how it can do it so quickly.
