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 mixed high/ultra settings as shown below.
Shogun 2 runs surprisingly well at these settings, and we can see that the HD5850 Xtreme solution manages to outperform the newer HD6790 cards with this particular engine. The newer card is slightly faster than the HD5830 however.
