For some reason when i'm playing multiplayer cod4 my ping is ridiculous. In the past (pre windows 7) I would get a good 40ping in most servers. However, after installing windows 7 and installing cod4 my ping is going crazy. All servers in the server browser show as 1000+ ping. When i'm in a server my ping drastically jumps from 150-999 at a fast interval.
Things I've Tried:
I've installed all the cod4 patches up to 1.7
I've disabled all firewalls and antivirus
Could this be a driver related issue? I tested my internet connection in windows 7 through speedtest.net and it was showing about 5 mb/s download.
What should I try next to try to diagnose this issue?
windows 7 rc 32bit
nvidia 8800 gts
amd athonx2 3800+
