I've had rFactor for years on my current PC and it has never given any trouble, I have reinstalled Windows 7 x64 in the past and rFactor has worked afterward until now. I've searched and searched and I've tried every solution that I have found but none of them have worked. My graphics card is a GTX 550ti and I'm led to believe that this is where the problem is coming from. Anyone out there know something I don't? Cheers, Ash Sowman.
