This quick and easy guide will let you make a temporary private session!
First open Task Manager.
Go to the “Performance” tab and click on “Open Resource Monitor” at the bottom of the program
Find “RDR2.exe” right click it and select “Suspend Process”. Keep it suspended for 5 seconds, then right click “RDR2.exe” again and select “Resume Process”
You now have a temporary empty session that you can invite your friends to or ride solo! It’s temporary because sometimes the game will move you to a session with players after a while. If that happens, just repeat the process. Hope this helped!
