Feature Overview

OptiFine Parity

Missing your favourite OptiFine features on sodium? Perfectly Optimized includes alternatives for many familiar features, such as shader support, connected textures, and zoom. Many resource packs made for OptiFine may also work, depending on the features they use.

Pre-Configured

You don't need to spend time changing settings or figuring out which configs work best. The modpack already comes with carefully prepared configurations, so you can install it, launch Minecraft, and start playing.

Still Feels Like Minecraft

By using this modpack your game will not look like different game, The goal is to make Minecraft more optimized and Perfectly Optimized keeps the familiar vanilla style while improving performance in the background.

No Unnecessary Mods

Every included mod has a reason to be there. The focus is on performance and useful features, not filling the mod list with things you don't need. This helps keep focused on what actually matters.

Updates and Improvements

Minecraft updates can bring new features, changes, and compatibility. Perfectly Optimized is designed to keep its configuration and included mods working together as the pack evolves. We try to update Perfectly Optimized as soon as possible whenever a new Minecraft version is released. However, some mods may take longer to update, which can delay a new release. If you don't want to wait, you can also check out the Beta or Alpha versions, as they may be available earlier. Keep in mind that these versions might have missing features, bugs, or compatibility issues.

How to install Perfectly Optimized

  1. This modpack runs on Fabric for Minecraft 1.21. The launcher you install it with sets that up for you.

  2. Download the .mrpack file from Modrinth.

  3. Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.

  4. Give the instance enough memory: most modpacks want 4 to 8 GB.

  5. To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
