All,
I am having performance issues in BF3. I have 2x Gigabyte HD 6850 GVR685OC-1GD Radeon 6850 video cards in Crossfire mode. I will post the rest of my system specs below.
Basically, Battlefield 3 runs better with Crossfire disabled. It is smooth as silk when running at 1920x1080 on a single 6850. But as soon as I enable Crossfire mode, my FPS drops pretty low when looking over the battlefield (long distance) or when I get into a lot of action with smoke/fire.
I have tried numerous things. Even wiping and reformatting my system. I first tried using the latest drivers for my motherboard (Gigabyte GA-MA790XT-UD4P) from their website. Same performance issues with Crossfire.
I've tried getting the latest individual drivers for each piece of hardware in my system (chipset, graphics, audio, NIC) - even tried AMD Catalyst 12.6 Beta.
Same performance issues with Crossfire.
I've tried AMD 12.6 CAP profiles for BF3.
Same performance issues with Crossfire.
A single 6850 runs much smoother than 2x in crossfire, which I would definitely not expect. I wouldn't think it would be my CPU since the game runs great with Crossfire disabled, unless the CPU isn't enough to push 2x 6850's? I am very tempted to just rip the second 6850 out...
The CPU temps hit up to the low 50's. The GPU temps hit low to mid 50's. The CPU idles around 37*C. The GPUs idle around 40*C.
