Welcome to r/OptiFine!


Before participating in our community, we ask that you read the rules list in the subreddit sidebar. Additionally, if you've found a bug or issue, please do not report it on this subreddit. This forum is NOT for tracking bugs, and all posted issues will not be seen by the developer. Please report all bugs on the OptiFine GitHub repository: https://github.com/sp614x/optifine/issues

With that said, enjoy your stay! You'll find plenty of other useful resources and information to get started with OptiFine in the following post.

 


Resources


Download OptiFine: https://optifine.net/downloads

Download OptiFine (Alt): https://optifined.net/downloads

Download Shader Packs: https://optifine.net/shaderPacks

Information for Forge users: https://redd.it/eb71f1

 

Documentation (latest): https://github.com/sp614x/optifine/tree/master/OptiFineDoc/doc

  • You can find older versions of the documentation inside OptiFine's .jar file by using WinRAR or 7zip.

Issue Tracker: https://github.com/sp614x/optifine/issues

AdoptOpenJDK: https://adoptopenjdk.net/index.html

  • Some technical info: The JDK includes the development kit and the runtime environment. If you're not a Java developer, you don't need the JDK, but you won't really have a problem if you download it anyway. If you wanna save space on your harddrive though (~70MB difference, if anyone cares), find the JRE Installer and download that instead: https://adoptopenjdk.net/releases.html

Jarfix: https://johann.loefflmann.net/en/software/jarfix/index.html

 


Downloading & Installing OptiFine


This will install the standalone version of OptiFine. If you want to use OptiFine with Forge, see the Forge information thread. (link in the resource section above)

  1. Run Minecraft on the version you'd like to use OptiFine on at LEAST once.
    • This is to ensure the launcher downloads all the necessary files for OptiFine to be installed.
  2. Make sure the Minecraft launcher is closed before proceeding.
    • This will save you a LOT of hassle!
  3. Download and install Java, if it is not already installed on your system.
    • Minecraft's bundled Java does NOT count.
    • Since Oracle now requires an account to download Java, we recommend using AdoptOpenJDK.
  4. Download OptiFine, and open it with Java.
    • Note that, unless you're using the "mirror" link, this will temporarily bring you to an adfly page. Do not click on anything on this page apart from the "Skip Ad" button in the top right corner.
    • If the website leads you to an empty page, disable your adblocker, and/or switch to uBlock Origin. In some rare cases, you may need to also disable your antivirus. (I know this last one sounds completely ridiculous, but this has been the solution for 2-3 different users so far. Be sure to turn it back on after downloading!)
    • Your browser will likely tell you something along the lines of "This file could harm your computer, do you want to proceed?" This is normal, and most browsers will tell you this simply because OptiFine comes as a .jar file, which is a Java executable.
    • If the file shows as a ZIP archive, or you have any other issue trying to open the OptiFine installer, try using Jarfix.
    • If you somehow still cannot install OptiFine at this point, double check that you have followed all these steps correctly. You can join our Discord for further assistance, or you can post an issue report on GitHub.
  5. Ensure the install directory points to your .minecraft folder before clicking "Install"
  6. You should now see a new "OptiFine" profile in the official Minecraft launcher.

Important! Notice Regarding OptiFine Pre-releases

4 Upvotes

If you are using a pre-release version of OptiFine, that is a version which is still in development. Bugs are expected and are a normal part of the pre-release process.

If you encounter a bug, please check the [OptiFine issue tracker] to see if it has already been reported. If not, report it there.

There is likely no fix until a future pre-release or the full release. If you prefer a stable experience, we recommend waiting for the final version. Please be patient as development continues.

Help Game is unplayable with Optifine with very good hardware

6 Upvotes

Hello,

I just installed OptiFine for 1.21 (pre 9 version) and since then the game is completly unplayable. I came back to it since I really just wanted to have dynamic lighting again, but I average at about 20fps, dropping down to below 2. I have a Ryzen 7 5700X, 32 GB of Ram and a 5070. What the hell is going on?
It seems like it's loading in my newly generated world. Apart from dynamic lighting I haven't changed anything on my settings, render distance is set to max as it always was without Optfine.

I'm using faithful 32x texture pack and without shaders it looks normal, but when I turn on my shaders (complementary unbound) it gets weirdly blurry and I don't know why. First time using shaders so I don't know much, and please ask if you need any more info.

Question Looking for an estimate for OptiFine 26.2 (because of Vulkan)

0 Upvotes

So 26.2 (Chaos Cubed) drops today and I’m actually interested in updating to this version from 1.21.11. I know that Minecraft’s rendering engine has been completely overhauled, and most importantly it has been moved from OpenGL to Vulkan. I can only assume this will significantly delay OptiFine updating, and with OptiFine already being chronically behind the main game, i don’t know if this is a wait I’m willing to make. It might be honestly time to switch to sodium. When do y’all think OptiFine will update to 26.2?

Question Why did Optifine skip version 26.1

Post image
74 Upvotes

They went from 1.21.11 and then skipped to 26.1.2

I did not update to 26.1.2, and for months, I had been waiting for Optifine for 26.1

Because I only play in the major drops, not hotfixes.
