R.E.P.O.: Potential memory leak in the game? (Workarounds)
Short answer
Suggested fix (unconfirmed): Switch from Linux to Windows until the developers patch the memory leak. Alternatively, monitor your RAM usage and restart the game every hour to prevent crashes.
The problem
The update has been really fun though I've had the game crash whilst in multiplayer lobbies due to my system running out of memory twice now. For reference I have 32GB of RAM and I'm only using around 8GB when Repo isn't open. It seems to trigger after we've been playing for around 3-ish hours.
Did this work for you?
