I have done my searches... on google and this forum. Nothing helps! As soon as i click play on steam. The launcher pops up. start the game, crash. Even before the video. "FalloutNV has stopped working." I already put up a support ticket, but I wan't to play my game now, not in a month when they finally get around to my question.

Verified Game Cache.
Tried deleting ini's.
Tried running in compatability.
Tried reinstalling it.
Updated Graphics Drivers.
Updated Sound Drivers.
Tried putting in that DX9 dll.
Tried turning crossfire off.
Tried banging my head against the keyboard.


Specs:
i5 2500k OCed to 4.5
2x Sapphire 6950's OCed and unlocked
8gb RAM
Windows 7 64 bit PRO

Run with only one of the graphics cards; CF and FONV are not particularly compatible without some custom profiles. Next, return all core speeds to the defaults.

I wrote that I did try turning CF off...
I'm not returning my core clocks to normal. Too much time and effort just for one game to work. It's not worth the FPS hit for my other games.
