-The game can crash i've pinpointed it to frame generation being turned on in the ingame settings. This needs to remain off.

-Textures being higher then medium. Causes performance issues. -Anisotropic filtering needs to be turned off.

-if you did change certain settings and get a crash on startup or black screen you need to delete the games config.xml file which is located in -(your SteamLibrary folder)/steamapps/compatdata/1340990/pfx/drive_c/users/steamuser/Documents/KoeiTecmo/Ronin

-This will allow you to start the game again and preload shaders also set the settings correctly.
