Well my computer is pretty new, but maybe yours is newer/more high end? I assume it also uses rendering, etc that PSX and what not doesn't so it'd have a varied effect on my video card (which is a piece, but can still run something like Fallout 3).
(Also, @Bojangles: The "You're all incorrect" comment was sarcasm. Sorry bout' the misunderstanding.)'
EDIT: I'm using Dolphin.
How about no!? You are an idiotic version of a baboon.
