I seem to be having an issue with the way FO3 detects my hardware. In the game launcher it's listing my Graphics adapter as an Nvidia GeForce 7900, even though that's not what I actually have. Couple that with the fact my frame rate has been chopped in half and you can see how this is a problem. I'm not sure how it started or what caused it to be honest. I've tried to get it to re-detect my hardware and that doesn't even work.

As you can see from the pic, I have an Radeon HD 7800 series. I'm trying to avoid a complete re-install, but we'll see.
