Hey, I got a little problem...

I like to host my own server rather than joining others, but after 20-40 minutes of hosting my server, the game will run slowly. The fps will be high(50+) but the game has a jerky feeling to it. If I try to minimize the game, or put it in a window, the game will stop responding. I then must restart my computer if I want to run Jazz2 again.

Any help or suggestions please!
