Optifine & shaders for Minecraft

  1. Get Optifine for the corresponding Minecraft version here: https://optifine.net/downloads

  2. Get your Minecraft install data location, here with the flatpak install from flathub: /home/locynaeh/.var/app/com.mojang.Minecraft/.minecraft

  3. Launch Optifine installer: java -jar OptiFine_1.19.2_HD_U_H9.jar and indicate the correct location of the Minecraft folder

  4. Find the wanted shaders, download the package (.zip) and move it to the shaders folder in the flatpak minecraft folder (the folder seems created after you try to look for shaders in-game)

  5. Select the shaders in Options > Settings > Shaders

  6. To uninstall, delete the version folder created by optifine.
