apologies in advance if this has all been covered already.
i've just joined this site for some help on getting shogun 2 working properly.

problems:

campaign map - can't see any roads, strange vertical colour smudges on the screen. no movement areas for armies. can't see the ocean.

battle - sky is black, have water effects but no water. on shader level low the sky is blue but the water completely dissapears.

what do i need to do to get this game looking proper? i have napolean and that runs skip free with graphics set to very high.

what am i suddenly missing that i was'nt for napolean?
