so today, I downloaded the latest video driver nVIDIA had that was compatible with Portal, and it's installed correctly, but I need to uninstall my old one, and I don't know how, and now because of this, my Portal game is all laggy:frustrated: anyone wanna tell me how to uninstall
Usually when you get a new driver it should overwrite the old one? That's a bit strange.. Google it, or maybe your computer is having a hard time with all the stuff you have on it. Check your disk space.
