turning scene antialiasing might slow down your renders, this is normal. Most graphic card do antialiasing by rendering a (at least) 2 times bigger image, that gets reduced. If you're rendering 800*600, in fact, the graphic card renders a 1600*1200 scene. Depending on your graphic card, that can be very slow.
