While playing soul reaver I noticed that every 15-20 seconds the game would slow down, almost like going into slow-mo. It doesn't fully effect game play but it is a bit irating. I must note I'm playing on the disk on my ps3 because my ps1 laser has burnt out. I have tired other games like blood Omen and tomba and they work just fine. Does this happen to others; is it just the game and is there a way to stop the slow-mo?
