For this build (including builds above 1.20.5) need Java 1.21 https://www.oracle.com/java/technologies/javase/jdk21-archive-downloads.html
This pack should make it easier for your game to work. It contains a small number of mods that are suitable for playing on the server, in the local world. This is my first pack, criticism is accepted!)

Basic Mods:
Sodium (a new mod aimed at improving the performance of the game, significantly increasing FPS in Minecraft.)
Very Many Players (A Fabric mod designed to improve server performance at high playercounts.)
IrisMod (An open source Sodium-based mod that adds support for existing shaders to a game with Sodium installed. The author declares support for existing shaders that are focused on Optifine.)
Concurrent Chunk Management Engine (It is designed to improve the performance of generating game chunks of the world, improve and speed up the loading and unloading of chunks, which should have a positive effect on the performance of the game, especially with a large number of installed mods.)
