Hey, unfortunately, there's no way to do this in game. You'll need to launch the game with a command line argument:
-force-metal
Viewing post in How do I switch to the Metal rendering API
So in the terminal at this directory, "/Applications/AShortHike.app/Contents/MacOS", using the command "./AShortHike -force-metal" should do the trick?
Is there anyway to check in game what rendering engine is currently running? Also is it definitely "-force-metal" and not "-force-gfx-metal" or "--force-metal"?
Thanks!
Edit: nm, it seems to be working.
