Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I am currently unable to get Crysis to use the 2nd GPU on my 3870X2, and my Crysis GPU benchmark numbers are almost identical to other mainstream website reviews I've seen of the X2, when they're reporting use of Vista x64. I have a feeling nobody is getting X2 Crossfire+Crysis+Vista64 working yet except with beta xfirex drivers perhaps.
So, yes there are issues with the drivers and/or game. I am installing UT3 at the moment so I will report back if there are any problems with that. Warcraft 3 and all Source and HL1 engine games are using both GPUs with cat8.2. Crysis is the only game I've seen that doesn't function correctly(And yes, v1.1 game reporting MGPU enabled, and forcing it enabled in cfg).
