Can you elaborate a bit more on "failing to launch"?
Does it give you an error? Does it start loading and then crashes?
Have you tried reinstalling the games? updating nvidia drivers?
Well, I got a little impatient
and decided to do a clean install of Windows, since I was about a week into this one anyway. I didn't have much to lose, and figured why not.
I'd still like to know why though just for future reference. The games start up, and then they just crash. Everything has the latest driver possible. That was one of the things I checked.
