Dont know where to post this so if it needs to be moved feel free. To start things off. i have a dell xps 410. 2.1 core 2 duo 2 gigs memory 256 geforce 7900 gs video. my friend has a dell 4700 2.8 H/T pentium 4. 256 ati x1950 pro. 3 gigs memory. My question is after we start playing a lan game. supreme commander to be exact. Only after 15 mins of play do the game slow down? Im the one hosting the game. i have a crossover wire linking both computers. We have the latest video drivers installed. Any help would be welcomed.
