What are some optimizations for the Steam Deck to make emulation even better?

These optimizations are entirely optional and but they can give you better performance on some more demanding emulators.

Click on Setup Utility
Click on Advanced
ChangeUMA Frame buffer Size to 4GB
Save and Exit

Setup a sudo password

What is sudo?

This is a requirement for many optimizations and solutions, it also makes your Deck safer. It enables you to run commands/applications heighten sudo privileges.

Go to Desktop Mode
