Just checked out the game last night. Plays quite well on my i5 3570k (stock settings), and 7870 LE (core OC to 1,200MHz). Getting 70+ fps in explorable zones, and 45+ in the city. I dropped the AA down to 8x from 16, didn't notice any improvement in fps. Using default settings which are maxed out and a res of 1920x1080. Decent game but I'll wait until it comes out of Beta to start playing, there's still some things that need addressed like switching toons, you have to log out of the game and log back in to switch toons. Other than that I rather liked the game, hopefully they'll add game pad support, as this game could be a good fit for a controller as well as mouse/keyboard.
