Currently while playing Opposing Fronts, I get about 30FPS while running Max Settings. I've tried adjusting for basic 4870X2 issues, such as disabling v-sync, but it remains at that average. I haven't tried major graphics tweaks, but disabling AA apparently does nothing. Every other game I've tried seems to run within the standards of benchmarks/other users, except this one.

I guess the question would be where's the issue? I've had comments on processor speed, but that doesn't seem correct.

Does the 4870X2 still use crossfire for the two chips? I think I heard somewhere that COH isn't good with crossfire, but maybe I'm completely wrong. What res are you running at?

I would also like to pose a question. How hot does the 4850, 4870, or 4870X2 get? Maybe it's clocking itself down to prevent overheating?

If it is a crossfire problem, it is killing performance. My old 7800 GTX could take Crysis on DX9 without too many problems, so i'd imagine even a single 4870 could crush it...
