Mine I play at 2560X1080 everything on MAX with 60fps…FPS just drop on full channel Cities and when I try to dash with swordman and try to open the map “M”.
I have just a GTX 750TI that is not too expensive and a I7 4700 and my computer can barely play The Witcher 3 on 1080p with everything low.
If You NEED so much higher fps I suggest You to low Your configs to the very low settings but try to keep high resolution.
Game may have problems with fps but it is nothing bad for PVE…since PVP áreas are propably instanced and very small compared to other maps i don’t think its gonna hurt anyone.
