omg tell me aboot it! Over me mates last night and loaded up GTA4 on the 360. I've been playing it a lot on PC and I was AMAZED at the difference. People **** the PC version off left, right and centre but DAM does it run better than the console (or at least on mine!).
Don't really like Vsync tbh either. Makes the games feel unresponsive to me.
That,s because Vsync is 2-3 frames behind in what is going on.
