I have had a look around the forums and can't quite find anything exacly like this problem. I am getting weird very small lag spikes. I have used teh shift f8 tool and it seems to go in time with my lag spikes. It can tick along below 100 down to teens then all of a sudden it can jump to anywhere from 120 - 500 when this happens i get the lag spikes and also a crackle from the sound. I get alot worse when i'm behind other cars. Any idea's or time ot buy a new nic card. I use my onboard nic card. Have not really noticed any great problems with other games.
