Block Artifacts appearing during realtime and renders

[dbrown9141]

Hello, I am getting these odd artifacts on screen that gradually increase. I believe it is a graphics card setting/issue since I have dealt with this problem before (just forgot how to fix it)- just reinstalled windows. Does anyone know the fix for this problem?- saw another post in general discussion with the same problem (no answers).

I am using 2 gtx 460's with sli disabled and an i7 920 (graphics driver 280.26)

planning to upgrade to keyshot3 but I need to get this sorted out first, thanks

Can you please contact support? I personally have not seen this.
