Here's my problem. My copy runs fine and all. it gets great FPS and everything, my problem is that everyone 30 seconds I get a series of massive lag spikes that stop my game from running for about a minute or so, then it returns to perfect FPS.
This doesn't only happen on Oblivion, it happens on all my Battlefield games, and most newer games.
And when I'm by myself in BF, it runs fine no lag spikes or anything.
