Optifine 1.21 / 1.20

While Minecraft is an ever-expansive and fun game to play in its original variant, a lot more can be added to it by installing mods and resource packs. One of the most effective and useful tools (mods) you can install – whether you want to keep the original flavor or add some uniqueness to your game – is the Optifine mod. Optifine is not a resource pack in itself. It does not change any textures in the game. It is, instead, a tool that allows you to adjust Minecraft to increase performance or visuals to your liking. For instance, it provides new settings in the menus that allow you to more freely adjust rendering distance and other factors that might affect how well your computer can run the game. It also allows you to use various resource packs with custom features. If you use HD resource packs and have seen major frame rate drops, see serious lag spikes in your system, or otherwise just need an FPS boost, Optifine HD will provide exactly what you are looking for.

Optifine can be used in both single player games and multiplayer servers. Be warned, though, Optifine HD only works in multiplayer games if the server’s host also has Optifine HD installed on the server. If this is not the case, Optifine will be disabled and you will not be able to use it. Another warning that comes with this is that some of the steps you can take to increase your frame rate will also make Minecraft less visually appealing to look at. You can disable clouds, the sky, stars, fog, and a number of other functions that make the game more visually appealing. All in all, Optifine HD is probably the best way to take more complete control of your Minecraft experience. You can adjust how textured and detailed everything is, from bare bones to top of the line graphics, based on what your personal computer can handle.

OptiFine should be compatible with all of these Minecraft versions: 1.21.11 - 1.21.10 - 1.21.9 - 1.21.8 - 1.21.7 - 1.21.6 - 1.21.5 - 1.21.4 - 1.21.3 - 1.21.2 - 1.21.1 - 1.21 - 1.20.6 - 1.20.5 - 1.20.4 - 1.20.3 - 1.20.2 - 1.20.1 - 1.20 - 1.19.4 - 1.19.3 - 1.19.2 - 1.19.1 - 1.19 - 1.18.2 - 1.18.1 - 1.18 - 1.17.1 - 1.17 - 1.16.4 - 1.16.3 - 1.16.2 - 1.16.1 - 1.16 - 1.15.2 - 1.15.1 - 1.15 - 1.14.4 - 1.14.3 - 1.14.2 - 1.14 - 1.13.2 - 1.13.1 - 1.13 - 1.12.2 - 1.12 - 1.11.2 - 1.11 - 1.10.2 - 1.10 - 1.9.4 - 1.9 - 1.8.9 - 1.8.8 - 1.8.1 - 1.8.6 - 1.8

How to install Optifine:

Guide last updated: 2022-07-22

Before we proceed with installing Optifine, you also need to have Java installed on your device in order to be able to run the Optifine installer. Java is available for Windows, Linux, Mac OS X, and Solaris. Get Java here.

Quick Java Installation Guide:

Click the image to open it full size in a new tab.

  1. Download Java from the official website here.
  2. Run the file you just downloaded and click Install.

NOTE: Optifine will only work with the Java Edition of Minecraft. Optifine does not currently work with Bedrock or any other edition.

And now.. OptiFine:

Please follow each step carefully if you have never installed OptiFine before.

  1. In the download section (located directly below this guide), you will find a link to the official Optifine website. Click on this link and you should be redirected to the developer’s official website.
  2. On the optifine website, you will see many different labels. First make sure you find the correct “Minecraft Version Label”. If you’re playing Minecraft 1.18.2, look for the appropriate label, then simply select one of the versions of Optifine under that label (we strongly recommend that you always choose the OptiFine HD Ultra editions. They usually have the most features) and click Download (or Mirror).
  3. If you clicked the “Download” button (step 2), then most likely you will first be redirected to an sponsor page with a short timer of 5 seconds. Just wait and click “Skip”. If you clicked the “Mirror” button (step 2), you will be redirected directly to the download page.
  4. Now, once you are on the download page, click “Download” again.
  5. Right-click on the newly downloaded Optifine installer file (should be in .jar format), select “Open With”, and then click “Java (TM) Platform SE binary”.
  6. A small installer window will appear, just click “Install”. After a while, the message “OptiFine is successfully installed.” will pop-up.
  7. Run the Minecraft launcher and click on the small arrow to the left of the green “PLAY” button. You will notice that there is a new version titled 1.19-OptiFine_HD_U_H8 (it may be different in your case depending on which version of Minecraft you are using and which version of optifine you have installed). Select this Minecraft Optifine version and click “PLAY”.
  8. Done. Now you have a version of Minecraft with Optifine. We hope the guide was useful to you, we tried to describe everything in as much detail as possible with screenshots so that you can understand it better. If you still have problems with the installation, leave your question below in the comments – either the administration or site visitors will definitely help you. But there should be no problems if you carefully read everything and do as it is written in the guide.

  4. awarhfgvhjsdbfsr

    can it work on Tlauncher ?????

    1. Tecker

      in Tlauncher, where you select the version, Optifine is built in for each version, where you can download it straigh away. Said version is recognisable like “Optifine 1.20”; “Optifine 1.19.3” together with other versions like “Release 1.20”; “Fabric 1.18” and “Forge 1.21” . It may not be for the newest version, since it hasn’t been released yet, but for almost every other version it is.
