I have a quad core 2.66 GHz 6 GB RAM GeForce 7950 GT 256mb. Whenever I play the game, it runs smoothly on medium settings and I have no other problems. My video, processor, MB, and ethernet drivers are all up to date, and I have no firewall but I do have a router. When I am in the game lobby, the pings are all around 100 ms for me, however when I go in game, I keep causing these bad lag spikes once every 3-5 seconds or so that make the game RMed. This does not happen to me in any other game. Any ideas on how to resolve this?
