I've played it on 2 different very good pc's and a 3 year old laptop. The pc's have to constantly reload the ui to get the framerate back to playable. Even then it's not maxed settings. The laptop is unplayable getting 20fps in ideal conditions on the lowest settings. The capital cities just rape all 3 machines. For comparison all 3 machines can play TESO, Landmark, FF, Blade and Soul perfectly, with the laptop having the settings turned down to medium.
They better do something, the beta community is obnoxious as fuck with the debug code, it's not optimized, re-install or whatever bullshit excuse they can come up with to defend it.
