Nvidia Setting - Help Required !

I'm currently running on
Intel i5 4670k @ 3.40Ghz,
8GB RAM
NVIDIA Geforce GTX770

and installed PoE on my SSD. I just want to know, how can i improve my PC performance on full party map. Is there anything i should change to reduce FPS drop on party game, sometimes i got massive FPS drop on solo gameplay as well especially on shock / burning ground map ? Here's my current graphic setting.



In game setting:
Full Screen Mode - 1920x1080
Texture, Shadow, Antialiasing - HIGH
Vsync - OFF
Post Processing - ON

Thanks !

if you have only one display then change "multi-play/mixed-gpu acceleration" to single display. Next change "power managment" to maximum performance, thats all what i changed for PoE.


Disable Shadows ingame.



by the way, PoE is bad optimized, thats why i make now a break, this fps and lag spikes sucks.
