HI, I can't seem to find an option in Steam to disable automatic updates of games. I can only tell it not to update until I launch the game. I don't want to update until my current PT is finished , because I 'm using mods which might no longer work. What should I do ?
Unplug web connection when playing BG3
You can use the Steam offline function, that way you can play the old patch without disabling your internet connection on your computer.
Personally I would try the old branch option that you can find in the beta tab on steam (when it's available), I assume that would let you play without going steam offline mode.
