Guys, I’m having an issue with my new 7970. I’ve been using it to play Far Cry 3, and it works very well for that. I disabled SSOA per someone’s suggestion, and I’ve been able to run everything maxed out with 3 screens with a very respectable framerate. I was thrilled at first, but then things started happening. I started to notice weird artifacts. Forgive my layman description, but this is the best I can do.
I assume that when textures load, there is a different set of textures for things that are a great distance, medium distance, and close distance. As I get closer to an object, be it a rock or a house, at some point it changes from a far texture to a medium texture, and then to a close texture. When the changeover occurs, I notice a weird checkerboard effect for the objects while it changes over. It is a very weird occurrence, and becomes highly noticeable. It seems that as time has progressed, the changeover becomes slower and more noticeable, but that could just be my perception of it changing as I notice it more, I don’t know.
Then the game started freezing. It would happen after about 2-4 hours of playing, and the image would be stuck on the screen, with a very small, very weird artifact somewhere on the screen. I had to use task manager at that point to close the game. Then yesterday, my screen went haywire, and a very strange full-screen discoloration occurred, with very bright colors all over the screen. When I alt-tabbed out of the game, the weird discoloration continued in Windows. I had to restart the computer to get it to go away. It looked similar to this:
I am really, really hoping that it’s a software issue, because I don’t want to ship this card back, but I doubt that. Do you guys think it could be an issue with Far Cry 3? It doesn’t happen when I play rFactor, or when I use the Assetto Corsa tech demo. I ran 3dmark 11 one time, and nothing happened then. I’ll run some more of those back to back and post back, but mill it over guys, and let me know what you think. I downloaded HWMonitor and the CPU temps look outstanding. GPU temp was 72 after a long (error free) session of Far Cry 3. Didn’t check temps after 3dmark, but I will, and post back.
Do you guys know of another benchmark I could use to really stress test the GPU, or should I just send the sucker back? I bought it about 20 days ago from Newegg. Any other tips?
No overclocking whatsoever on any component, cleaned and dusted the case really well before I put the new card in, adequate airflow, really good fans, all fans working, relatively new PSU.
