Shogun 2 is set in 16th-century feudal Japan, in the aftermath of the Ōnin War. The country is fractured into rival clans led by local warlords, each fighting for control. The player takes on the role of one of these warlords, with the goal of dominating other factions and claiming his rule over Japan. The standard edition of the game will feature a total of eight factions (plus a ninth faction for the tutorial), each with a unique starting position and different political and military strengths.
All settings are pushed to high and ultra with hardware shadows and SSAO disabled.
This is a very intensive title and one that nvidia still need to optimise for fully. Nevertheless, the performance results are very good from the GTX580, averaging 35 fps and dropping a few times into the danger zone. A little more tweaking with some of the image quality settings would raise the frame rates a little to compensate.
