hello all, im facing FPS lag when 4 ppl in a party to NEST. (Saint Heaven and Lotus, yes, im facing the same problem too when thr are a lot of players.)

when im solo for dungeon, it is running like normal. no FPS lag at all.
I try to research on google before this. But sad, no solution tat could help to fix tis.

*No others program running
*ALL latest firmware & Driver version
*DN installed in SSD
*Running Windows 7 x64 SP1

and here is my Desktop SPEC:

AMD FX-8150 @4.23Ghz
AMD ASUS HD7850 2GB DC2
Gigabyte 990FXA-UD5
Corsair Force GT 120GB SSD
2*2GB Corsair Gaming RAM 1333Mhz
2*2GB ADATA Performance RAM 1333Mhz
Cooler Master M600w Silent PRO PSU

When running DN, i try to open Task Manager,
I notice that CPU usage arround 18-22%
and there are only 1 core in high usage compare the other 7 core
