Possible to use more computer resources?

[Norack]

I run the game at 1920 X 1080 resolution. I guess I overstep when saying I bought the best CPU, I bought the best one that I could afford its a AMD Phenom II X6 1090T. Also I found a new windower program and am currently using that and it is running almost like it does when in full screen with 20-25 fps in very crowded areas and 30+ fps when running around outside now. I am just nit picking lol I just like playing games like solo play on consoles I guess. I just have to get use to it i guess, or wait till 2.0. I am not so much worried about the drop in FPS as the fact that on the back of the game it recommends a quad core? but is a singlethreaded game <,< that makes no sense to me. And they recommend 4 gigs of RAM but no matter what my game is always using 1.5 gigs of RAM. Like when the game runs smooth like a console game it uses 1.5 gigs of RAM, when it obviously needs more, it just uses 1.5 gigs of RAM and never uses more. Just curious as to why they recommend 4 gigs when the game cant use more than 1.5? idk though <,<

I also hope that in 2.0 they make this game 64 bit compatible, and not just make this game run on WoW64, that would be so sweet.
