OS?
PC ---> 3 GHz, 2 GB RAM, 512 mb video (maybe ruined i think cuz of those screens!)
When i enter on luncher options and set "Auto set" to my PC specs everything going on hight, but i play on low and you see my gameplay... This done when i fight and in middle of fight it's prevents me to play as i can.... On native i don't have those problems. And my fps almost always 60. But don't like native.
In every server over 10 or 20 ppl start get low fps and this in fights.
