About this project

What does OptiFine Checker add?

The license of Optifine prevents it from being distributed, but there are times when players may not install Optifine manually to the modpack's mod folder.

This mod will remind players to install Optifine when it detects that Optifine HD is not loaded properly.

Only Forge is supported, as Optifabric also alerts players when Optifine HD is not detected.
