Optimalsation
The highest performing 1.21 modpack
Quick answer
Which Optimalsation release matches Quilt?
FPS Only is a complete pack release for 1.20.4 with Fabric, Quilt. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 37 mods in this pack file.
Pack setup
How should I set up Optimalsation for players and a server?
Use FPS Only as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for Optimalsation?
FPS Only on Quilt. The pack contents and setup notes below stay tied to that release.
The selected pack release is FPS Only. That file is for Minecraft 1.20.4 with Fabric, Quilt. It contains 37 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
About this project
What kind of pack is Optimalsation?
What Sets 'Optimax' / 'Optimalsation' Apart?
There's many modpacks that have optimization mods in them but they're either bloated with other additional content unrelated to performance or they only have a few mods.
This modpack is a all-in-one of every FPS mod as long as they're 1) compatible with each other and 2) it actually helps performance (some mods don't have the results they claim or another mod does something similar but better)
Shaders & RTX
The mod also includes performance-friendly shaders with further optimizations so if you wanted to use shaders during gameplay try them out!
Research & Testing
Months testing different combinations of incompatible FPS mods to see which ones gives the greatest performance went into this and I can confidently say that this exact combination is the smoothest way to play newer versions of Minecraft.
Categories / Type / Tiers / Versions
FPS Only
- Includes ONLY mods that boost performance
FPS + QoL
- Includes all the mods the 'FPS Only' version does (FPS boosting) but also adds some basic common quality of life mods most players add to their own modpacks that DON'T effect gameplay (e.g, Mouse Tweaks)
FPS + QoL + Tweaks
- Includes all the mods the 'FPS + QoL' version does (FPS boosting & QoL) but also adds some mods that may affect gameplay, however these mods don't add additional content to the game, they may change existing vanilla content/mechanics slightly to be more user friendly
Permissions
I've designed this modpack into these categories so people can either use these mods themselves to enjoy the game, or so they can use this modpack as a baseline to create their own modpack. I thereby grant other authors to upload their own modpacks using this as a baseline/foundation, I do ask for credit so other people can find the source however it's not required
