The original bug report :  The fix that worked for me  :  1. I had EasyAntiCheat_Setup.exe and ww3_launcher.exe running as administrator, I removed that. 2. Verified the game files. (I don't know if step 1 and 2 are really necessary but that's what I did) 3. Enabled Driver Signature Enforcement by running the following commands with administrator rights (run cmd as admin)  bcdedit -set TESTSIGNING OFF bcdedit -set NOINTEGRITYCHECKS OFF bcdedit -set DEBUG
