Does anyone else ever have this problem, or is there something wrong with my game/console?
To answer your question, I haven’t noticed any real lag in Dirge of Cerberus, so it may be your console/disc. Check the back of the disc, and make note of any scratches, smudges etc and wipe the back with a soft cloth/tissue. Console wise, whether it’s a fatboy or slim PS2 doesn’t matter, but the laser lens may need cleaning. You can buy at any video store etc a laser lens cleaner disc, which cleans the lens. Give either of the above a try, if it still lags after that, I’m not sure what your problem could be… (Apart from playing that crap that is).
@Axmann: However, what Mysterwii suggested is a valid option. Find another copy (either a friend’s copy or go to a video store) and give that disc a try. If that works, then you’ll have to track down another copy.
Also, sorry for wrong section. Didn’t see the "FFVII compilation discussion" area. Thanks for moving.
