Performance Only
The modpack specifically aimed to eliminate stutters
Quick answer
Which Performance Only release matches 26.1.2?
Performance Only - 26.1.2 is a complete pack release for 26.1.2 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 28 mods in this pack file.
Pack setup
How should I set up Performance Only for players and a server?
Use Performance Only - 26.1.2 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 Performance Only?
Performance Only - 26.1.2 on 26.1.2. The pack contents and setup notes below stay tied to that release.
The selected pack release is Performance Only - 26.1.2. That file is for Minecraft 26.1.2 with Fabric 0.19.3. It contains 28 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 Performance Only?
I hate stutters of all kinds and minecraft for a very long time has been full of them.
So over the course of a couple years and a couple computers of varying specifications. Ive got to know what makes or breaks my framerate.
This modpack is a result of whats worked for me over the years.
This modpack doesn't add, remove or edit anything that alters visuals hence the name "Performance only".
That stuff is all up to you!
Benchmarks with other modpacks
How I benchmarked:
Latest 1.21.11 pack available was chosen.
The modpacks were loaded on a seperate world that were traversed on for ~2 minutes then another world with the "fpstest" seed was loaded, teleported using "/tp @s 0 100 0 90 0" Waited for about a minute to warmup again. Then started moving forward also starting CapframeX's capture
Settings were the same across all modpacks (32-RD 8-Sim no DH, Voxy, vsync or fps cap)
Take these with a grain of salt every computer is different!!!
My specs:
RTX 4060TI ryzen 7600X 32gb ram (12gb allocated)
Versions <26.1
In minecraft versions below 26.1 the JVM chooses G1GC as the default garbage collector.G1GC causes stutters due to it relying on pauses to garbage collect.
I would recommend adding these to your jvm Arguments (REQUIRES JDK 21+):
- -XX:+UseZGC -XX:+ZGenerational
ZGC is the new default collector for minecraft versions 26.1 and up.
