On most platforms I would expect windowed-mode to be slightly slower than 
full-screen - if only for the reason that UAE gets the display to itself in 
full-screen mode and so there's less clipping, layering, or whatever for the 
graphics system to take care of. 

On OS X, the difference is substantial, however. This is because, in windowed 
mode, the rendering has to go through the Quartz compositing layer. 

Using OpenGL to render UAE's output to the screen may improve things in 
windowed mode. I plan to implement this for version 0.8.28 (or whatever I end 
up calling the next version).
