Ideally you wanna be shooting for a steady 60 fps, but realistically if you can achieve a steady 30fps for a game like star wars your doing alright. In normal pve you can easily achieve 30-60fps, the problem comes in combat with PvP and operations for example. In PvP if you can get a steady 30 fps your doing really good for ureself :P
Thanks for your reply. My FPS usually ranges from 90 to 110, so I guess I won't be complaining any time soon!
