Hey!
This message about TapMinigameInputs is not related to the visuals, it's a missing reference on a VR input. I've silenced it in the upcoming 1.7 to avoid confusions.
Can you try setting the game to "potato" quality, and maybe reducing the resolution at well?
How much RAM does your M1 have?
Also, are you 100% sure it worked in 1.68?
