Runs ass on linux mint i get less than 30 fps meanwhile on windows it runs flawlessly at 1000+ fps
This is simply the launcher for the Java edition (as well as Minecraft Dungeons) except this version is often a bit out of date and thus doesn't launch the game until the apt-team approved of the new version. Which I think is not worth it, personally. You can download Mojang's own Linux launcher from launcher.mojang.com/download/Minecraft.tar.gz as of writing.
on windows runs fine but on MINT! it runs very laggy and is at 20 FPS (windows 320 FPS)
Mint 20 Cinnamon: Nothing happens after install. Tried both the Software Manager version and the one from Minecraft.net. It appears in the system menu but clicking it has no effect. I got MC working eventually by installing it with Snap. "sudo snap install mc-installer"
It works fine but once installed it'll let you know their is an update to the launcher which you then download from the Minecraft site so it'd probably be best to just download it from there
on XFCE running mint 20, and going to Minecraft website using gdebi installer allows you toget rid of the update launcher message.
