I've seen a thread about this before but no real answers on it.. So going to ask again.
On Silent Hunter: Wolves of the Pacific U-boat Missions add-on, during the end of a patrol when I try to time compress, up to 128 it starts getting really jumpy and anything past that it's like 0 FPS all the way. When on Silent Hunter: Wolves of the Pacific, the normal one, it plays fine and no matter what time or when, I can have time compression to 8162 or whatever it is and be fine.
It's not my computer's ability to handle it. I have a i7-920 core, GTX 295 gpu, 12GB triple channel memory, etc. Just weird that on U-boat Missions add-on does it but not the original SH IV.
PS: Would also like to add that it randomly crashes as well in navigation map and when I try to exit to windows, it crashes and get the lovely "Silent Hunter has stopped working" thing.
PSS: I also bought both versions of the game off Steam. My computer is up-to-date with everything, SP2, and all my hardware is up-to-date.
