Well, I can see part of the issue. NVidia chipset motherboard with a Radeon video card. Buddy of mine tried it the other way around, and had same issues. Major FPS loss in games which caused a lot of screen lag amongst other issues. He went out and bought an ATI card, and had no issues whatsoever. Even got a cheaper one than the NVidia he had. 1st I'd goto http://www.nvidia.com and get the latest drivers for your motherboard chipset. If still having issues, if it is not only continuum, i'd try getting an nvidia video card, or borrowing one, and see if the issues go away. Also, I went through the trouble and here is a link for your Ethernet Adapter Drivers: ftp://ftp.dlink.com/NIC/dfe530tx/Driver/d...er_10152001.exe Looking now, I also see you have messenger plus running. Try closing it when you run continuum, and see if anything changes. Both of my brothers use to have issues with it and games, Continuum being one of them. Reason I've never used it myself.
