So I tried the CRP optimization and I tried running the game in windowed mode. Both seemed to work for a short while but the game still crashes frequently. I finally caught the error prompt but now it won't let me take a screenshot, as if the game is trying as hard as it can to anger me. I will type out the contents of the error prompt instead.
Runtime Error!
Program: ....mb_warband.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
A pretty standard error prompt, not sure if it is any help. I should probably take a break from this game because no "game" should cause this much frustration.
