I know how to solve the conningtower problem.
The original download puts the tower files in
C:\Program Files\Ubisoft\Silent Hunter 4 Wolves of the Pacific\Data\Textures\TNormal\tex
Because you're PC is for whatever reason using low res textures you should place these dds files in
C:\Program Files\Ubisoft\Silent Hunter 4 Wolves of the Pacific\Data\Textures\TLowRes\tex
It think that will work.
Have you tried to select all options. Quit the game. then restart.
If that does not work. It must be in the cfg files somewhere..
I would do a fresh install with patch 1.2 and nothing more.
So far you're the only one with this problem.
@Captain Cox.. which cfg file tells the game what options to use ?
Sooner or later we will get it fixed for you !
Everybody deserves to play this great game in all it's glory !!
You're close to Rotterdam, Holland ?
