My PC is a ASUS MB Z87 chipset, 8 GB RAM, SSD HDD, and Geforce 780 VGA. It is not strong enough to execute the larger maps in CMBN Great Swan fluently! I wonder if it is something with the settings in my PC or if I really need a stronger PC? And if, what is then the bottleneck? Would a z160 chipset og a GFX 980 solve the issue?
