I have latest revision 12 inch powerbook (1.5ghz) and want to run EVO (in classic, not through EVN, because I want to play a couple of the TC's), but it is a little choppy. Basically it runs perfectly fine until you get about 4 ships on screen, when it starts skipping a little. Is there any way to make it run a little more efficiently? This is with no other programs open or anything, either. The original EV is even worse, I get like 2 or 3 FPS with nothing going on at all.
