How to use MangoHUD
Please see this comment: flathub/org.polymc.PolyMC#13 (comment)
How do I run MC on a hybrid GPU system with a dedicated NVIDIA GPU using Prism Launcher?
The flatpak includes a prime-run script, which when set as the wrapper command in instance settings, runs MC using the Nvidia GPU.
Soon this should be unneccesary, as it has been fixed in the master branch of the launcher already.
