Extreme Optimization!

Highly recommend these mods, not added to the modpack, because they do not correspond to the concept of extreme optimization and "Base", but may be more useful than others QoL mods:

Fastload - Changes some crucial parts of world loading to speed it up.

NoTelemetry - Disable the telemetry introduced in 21w38a.

NoChatReports - Strips cryptographic signatures that since 1.19 are attached to every message sent in the chat. Removing them makes it impossible to track and associate your chat messages with your Minecraft and, by extension, Microsoft account.

AntiGhost - Get rid of ghost blocks by requesting resends from the server.

ModelGapFIX - Fixes gaps in Block Models and Item Models.

CullLeaves - Culling leaf blocks, providing a huge performance boost over vanilla.

CullLessLeaves - Instead of leaving just the outer layer of leaves, Cull Less Leaves also renders a certain amount of layers defined in the config.

CullClouds - Small optimization improves clouds building way to not render parts which you cant see to increase fps.

JEI - Item and recipe viewing mod for Minecraft, built from the ground up for stability and performance.

REI - JEI alternative.
