OptiFine 1.18 is one of the major updates of OptiFine that is released for Minecraft Java Edition 1.18. It is a stable release as opposed to the latest OptiFine version which is in its preview (beta) state and does not support Forge. If you are still on Minecraft (JE) 1.18, you can also use OptiFine without updating to Minecraft 1.20.

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.
