elrasho it's an ATI Xfire driver problem. If they fix the drivers Xfire 5850s will max this no problem.
I really do hope so mate.
That's exactly the same problem I was having, sudden drastic drops of FPS to 1 every 10 seconds or so. As mentioned previously upping to 8GB of system RAM has completely eradicated it.
Played for around 2 hours last night, not a single instance of it.
I realise that it doesn't really make sense, what with there being plenty of people using 4GB ram with no problems, perhaps there's some sort of memory leak somewhere that affects certain systems?
I'd try that before changing to different GPUs, memory is dirt cheap at the moment anyway and could well sort it out. It did for me!
It is strange how upping to 8GB fixed it for you, are you running at Ultra settings? I would get more RAM but in order to fit another g.Skill 2GB dimm I have to take my Artic Cooling Pro 7 CPU cooler off, and that is a massive ball ache!
