About this Modpack

Modpack is undergoing slow renovation 🔃!

Besides a pure FPS boost, now tries to account for in-game situations, such as the use of block entities that can cause lag, and so on. Each mod goes through a multi-stage checking process and verified with trusted developers. In case of issues, I try to stay in contact with the developers of the respective mod. If you're surprised that some mod isn't here, things might not be as clear as you thought.

Hope I can help in the swamp of slop 🥀


Modpack is partially influenced by MC-Optimization-Guide.

If you've ever been looking for a list of thoroughly vetted mods, this might be the place.


If you can allocate 8+ GB of RAM to Minecraft, I can suggest my client Java Arguments.

I'm not fully sure of their correctness, but they've been tested for about half a year without any issues. However, I'm sure they can be improved or fine-tuned to perfection.

TL;DR: Use this if you want to eliminate freezes.
preferably use with GraalVM 25+. If it fails to launch - outdated Java or conflicting JVM flag.

Want to squeeze every fps out of your minecraft?

Don't need any extra mods, and only care about FPS? Right place! Extreme Optimization! modpack assembled to get the maximum possible FPS.


Other Modpacks

According to my observations and life experience, many modpacks add something of themselves, some improved cursors, effects, new sounds and so on, but this is not about Extreme Optimization!

But what exactly Extreme Optimization! do?

I decided to make it "modular". You download the base , its whole task is to squeeze out absolutely every FPS, but what about "modularity"?..
