In-Game

• You will probaly want to configure Controlify to your liking (if you use the Nintendo layout in Steam settings then you need to change the inputs!!!)

Out of the game

• Because the mod uses C2ME, you will likely want to allocate extra ram to minecraft. On my Steam Deck I allocated 8G but that is probaly overkill 😅.

• You can also set JVM arguments

• There's a thing called CryoUtilities that may improve your performance, not sure though.
