I am trying to play Vegas 2 over a LAN, and both computers are able to play the game just fine single player. But when I make a LAN game, my second computer becomes unplayable (only a few frames per second). It will say the ping is low at the join screen, but as soon as they connect then the second computer goes to crap.
It doesn't matter who hosts, it is always the same computer that gets the lag. If I start a game with computer #2, it is smooth until the other player joins and then it immediately slows down.
I had this same problem with Ghost Recon 2 and it was never solved.
Any suggestions? I've tried reinstalling, not patching, patching, opening ports (shouldn't matter for LAN though, right?) and nothing makes a difference.
