lol, well you're right about the premium and basic thing. I might be wrong, but I think basic is more graphic friendly due to the missing Aero glass effects.
no, I do not mean change resolution on your desktop, I meant in the game, but if that doesn't do anything, I'm stumped. I really don't know what else you can do.
WoW is a very interesting game to run. You can run it on pretty simple PCs, but to run it perfectly, You're gonna need some good shtuff.
I really am not sure, you should be able to run it. Hopefully someone else has some ideas?
