Now save the file by pressing the Ctrl + S key combo.Īfter making the following changes, try to play Fallout 3 in the compatibility mode on Windows 11.After doing so, in the new line, type iNumHWThreads=2.In this file, search for the following value bUseThreadedAI=0 and change the value from 0 to 1.Double-click on it to open it with Notepad. Now search for the falloutprefs.ini file.
