mirv_gameoverlay enable 0|1

• 0: disable
• 1: enable (will only work if it was enabled initially)

Command that allows to disable / enable the Steam overlay in-game. This command may be useful if you record with startmovie, as recording with mirv_streams ignore the overlay by default already. Please note that this will not disable Steam notification sounds, but those are not recorded by startmovie anyway.
