Hi SkateROck, just wanted to let you know I found fix for this, well one that worked for me anyway.
I tried about 100 different things to get this artifacting glitch fixed and this is the only thing, in this order that did it for me.
I have an XFX 7970Ghz Edition so if you have an AMD card give this a try. Go to Control Panel > Programs and Features > Add or Remove a Program > Uninstall AMD Catalyst Control Center & any other AMD/ATI programs you have there > Select custom uninstall and make sure everything is selected > once everything has been removed go to C: and delete the AMD folder > then Program Files and delete the ATI Technologies folder. Make sure you download the Catalyst 13.1 driver and then restart the computer before you try installing it.
Upon restart locate the 13.1 driver installer and run it, install everything on it and that's it. Artifact free gaming
As I said this worked for me, I scoured the web too it seems that other people are having this exact issue and its related to the 13.2 beta 5 drivers that are currently out. It's probably possible to roll back to the 13.2 beta 4 drivers too but I haven't tried it myself, I found something that worked and ran with it.
Hopefully this helps you. I know how frustrating this problem is. I had just bought my 7970 about 10 days ago and had this issue from day one was about thinking about even RMA'ing my card. Good luck to you.
