OptiFine 1.16.5 is an older update of the OptiFine mod released for Minecraft Java Edition v1.16.5. It is a stable release, unlike the latest OptiFine which is mostly in a preview (beta) state. OptiFine 1.16.5 supports Forge. If you are still on Minecraft (JE) 1.16.5 but for some reason you cannot update Minecraft/OptiFine then we recommend downloading OptiFine 1.16.5.

OptiFine improves Minecraft Java Edition’s performance by optimizing Minecraft’s standard coding. It adds options like FPS boost, FPS control, configurable animations & details, faster math, etc. These options help it boost performance. It also has support for Minecraft shaders and textures packs that modify Minecraft’s visuals to a great degree.
