holger1405 Thanks for getting back to me.
1) Check Health: No errors.
2) Restore health: Took a long time but it eventually completed.
"The restore operation completed successfully. The operation completed successfully."
3) Windows Resource Protection did not find any integrity violations.
FYI: I've just tried two other potential fixes:
- ticking "Run as administrator" in the game exe file's Compatibility tab
- ticking "Run this program in compatibility mode" (Windows 7)
Neither of those worked either. Trying out the DPI settings. (I think I tried those before but am trying them again.) EDIT: These didn't help either.
