To me, it sounds like something else is your problem.. Could be internal bandwidth issues, or some process, or a driver that is causing issues. Are you playing over a wireless connection?
I agree. I think you might have bandwith issues or maybe you need to double check your setup. Are you wired or wireless?? What's your router settings?? Have you tried different channel setting (1, 5, 6, 7, or 11)? Have you tried uninstalling & reinstalling video card driver & Wi-Fi driver??
If you're wireless - Goto, start > settings > network connections > right click on local area connection > properties > configure > advanced > and make sure property is set for b or g, long tremble, 54 Mbps, channel settings.....etc
