yeah tried that, they're both using the same version and such.
and dailup? 1st off like I said it's lan, using a direct lan line so pretty much no lag at all. and 2nd, I was never on dial-up. I'm using a high speed satellite connection. it's about as fast as DSL but there's like a 3 second data transfer delay from satellite to ground which ruins it for gaming....
anyway, you think it would have anything to do with using different OS's? I'm using XP and my bro is using Vista.
I've also modded the game a bit, it's not much and really shouldn't affect the game, I just replaced some of the weapon models with my own creations and changed the weapon positions and replaced a few weapon sounds. I transfered the medded files to my bro's Game directory also so they're set up exactly the same.
thanks for the replies guys.
