Extreme Optimization!

!This modpack won't have a Vanilla Launcher version, due to raw mods that need constant updating.

!This modpack - FABRIC. Since version 1.20.2 is not very interesting, many mods have decided not to update to this version, so there are some problems, which led to Fabric direction, + in general there much less mods, on the one hand because Mojang well optimized Minecraft, on the other hand because mods are not updated, or I have questions to them, in any case, the mods that I have "in question" below:

Highly recommend these mods, not included, because they don't match with extreme optimization concept (or other reasons) and "Base", but may be useful:

Nvidium - Fast nvidia only rendering engine for sodium. (don't know how it will work with newer sodium versions, but I'll leave it here just in case).

Video Tape - Fixes GPU-related memory leaks.

Lithium - No-compromises game logic/server optimization mod. (did not add because I do not know how well it works with new versions, my bad, in any case, do not want to add it if the difference will be in 1 fps, or in 1ms chunk generation)

Noisium - Optimises worldgen performance for a better gameplay experience.

Enhanced Block Entities - Reduce FPS lag with block entities, as well as customize them with resource packs.

Entity Culling - Using async path-tracing to hide Block-/Entities that are not visible.

NarrusYeetus - Remove the pesky narrator and all the errors related to it.

Raknetify - A Fabric mod / BungeeCord plugin that uses RakNet to improve multiplayer experience significantly under unreliable and rate-limited connections.

RailOptimisation - A simple mod that makes powered/activator rails turn on/off up to 4x faster. Fix vital crash.

Server Pinger Fixer - Improves pinging speed of the multiplayer server list.

VanillaIcecreamFix - An updated version of Runemoro's VanillaFix and also ported to the latest version.

Get It Together, Drops! - Сan significantly improve performance in areas with lots of dropped items.

Let Me Despawn - Improves performance by tweaking mob despawn rules.

LibreExpFix - A small mod that fixed experience bug after teleporting across dimensions.

REI - JEI alternative.

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.
