Anyone else having issues with Crossfire? Bought a second 6870 recently, both me and a coworker (5770's) have the same issue. Running the latest CCC and CAP 12.3 it is as though the hard drive is constantly being accessed and the game will stutter at first and at various times. It is as though the system is going to the hard drive all the time. My coworker thought it was his new drive until I got my second card and had the same issue.
Went back to driver 11.12 and Cap 12.3, same issue. Removed Cap 12.3 and things got a lot better, though still a bit of stutter here and there. Tried driver 12.3 and 11.12 Cap and it was better but not great. So far the best combination seems to be 11.12 for both driver and Cap, but still seems as though the drivers are buggy.
With either CCC and/or Cap 12.3 installed 3dmark 11 shows a very poor CPU/GPU combined score. Less than 50% than with 11.12 installed. And with 11.12 FPS did increase. So it seems it is definitely a driver issue.
Temps are good. Not sure about my coworker but both my slots are x16.
Basically just wondering if others are seeing the same issue, and what drivers/Cap are you using?
