I run a single 7850 HD in my system.

When I first started playing I was able to play for the most part alright. (only 40 fps though) through early access I started getting huge drops in FPS randomly (i'm talking 5-10 fps -- 100% unplayable) and it was driving me crazy.

So the other day I went ahead and downloaded the beta software for my card and for the first day I was running beautifully at max with 60 fps. Fast forward to today and the max FPS I can run at is 45 and about every 2 minutes my FPS drops to 5-10.

I even went as far as putting the graphics settings as low as they possibly go (grass off, no shadows, all physics disabled) and it STILL happens.

I ran the benchmark and I scored over 6000. What gives?
