Client / Single 1.12.2 Forge Java 8 ⛈️
release9 апреля 2025 г.Reminder: after downloading modpack, you can update mods to the latest versions if your launcher supports this.
Huge thanks to MeatballCraft modpack for their additional optimization guide.
If you need a zip archive (jars), use converters from mrpack to zip - they will recognize and archive mods.
Client / Single version = mods to increase FPS, speed up chunk loading, enhance control of game settings, and reduce memory and CPU usage, as well as optimize other logic (combined, since many mods are used both on the server and on the client).
A huge thanks to Opticraft for the incredibly helpful explanation of the current modded 1.12.2 situation.
Extremely recommend using Get It Together, Drops! if you're planning to dig a lot of blocks (ideally, live on a skyblock or in a void world, or something similar).
Some configs have been changed.
Configs I recommend checking or adjusting
BlahajASM (especially: removeForgeSecurityManager, classCaching).
Forge itself (especially: alwaysSetupTerrainOffThread).
Some mods are from other sources, so they may not update automatically. It is recommended to check after downloading the modpack whether they have been updated:
Highly recommend these mods, not included because they don't align with Extreme Optimization! concept and "Base" 
/ there is a chance that their optimization has already been implemented by another mod(s) / other reasons, but may be useful:
!Don't forget to check the dependencies and notes.
Sledgehammer - Smashes the stupid out of the client & server (actually, a really good mod, but requires meticulous configuration tuning to suit each user's needs).
Had Enough Items - Item and Recipe viewing mod for Minecraft with a focus on stability, performance, and ease of use (obviously, this is not just an optimization mod, but I can't leave out the fact that there's a JEI fork).
Relictium - Fork of Vintagium, which is a fork and backport of Sodium (decided to use Nothirium instead, but you can try).
Vintagium - Unofficial Fork and backport of CaffeineMC's "Sodium".
Valkyrie - Designed to optimize client-side operations while simultaneously introducing some valuable features.
Particle Culling - Stops rendering particles that the player cannot see (already fixed by other mods + a truly huge number of particles is required to start causing issues).
Entity Culling by tr7zw - Using async path-tracing to hide Block-/Entities that are not visible (outdated).
Entity Culling by meldexun - Client-side performance mod which aims to skip rendering of hidden (tile-)entities. (especially recommended for modpacks with massive dungeons with spawners).
PolyPatcher - Full of Vanilla bug fixes, Quality of Life improvements, and performance enhancements (too much that could negatively affect compatibility with optimization mods and huge modpacks in general, plus Universal Tweaks is already in use).
Born in a Barn - Fixes a Minecraft bug where Village doors keep chunks loaded (might already be fixed by other mods).
Fix Experience Bug - Fixes bug where experience does not display (and cannot be used) after changing dimensions (might already be fixed by other mods, or you might not encounter it at all).
Redirectionor [Retro] - Replacing references to element values in enum classes with static final field values references.
* "Dependencies" may not show all the mods.
Client / Single 1.12.2 Forge Java 21+ ⛈️
release9 апреля 2025 г.Reminder: after downloading modpack, you can update mods to the latest versions if your launcher supports this.
To make everything easier, Cleanroom Relauncher mod is used - but I still recommend a native Cleanroom (full guide).
Huge thanks to MeatballCraft modpack for their additional optimization guide.
On a personal note - make sure you really need Fugue and Scalar, as well as MixinBooter and ConfigAnytime (maybe you can safely remove / skip them).
If you need a zip archive (jars), use converters from mrpack to zip - they will recognize and archive mods.
Client / Single version = mods to increase FPS, speed up chunk loading, enhance control of game settings, and reduce memory and CPU usage, as well as optimize other logic (combined, since many mods are used both on the server and on the client. However, hosting services cannot work with Cleanroom Relauncher mod, so the Server version remains separate (as of now)).

Server 1.12.2 Forge Java 8 / 21+ Guide ⛈️
release8 апреля 2025 г.To run server on Java 21+, Cleanroom is used instead of Forge (full guide).
Huge thanks to MeatballCraft modpack for their additional optimization guide.
Just download the modpack if you need Java 8. For Java 21+ - make sure you really need Fugue and Scalar, as well as MixinBooter and ConfigAnytime (maybe you can safely remove / skip them).

Server / Single 1.21.1 NeoForge ⚡
release10 марта 2025 г..2 - updated some mods, tweaked configs.
!If you are planning to play in singleplayer, you need to combine this with the Client version.
!If you need a zip archive (jars), use converters from mrpack to zip - they will recognize and archive mods.
Server version = mods to speed up chunk loading, reduce memory and CPU usage, as well as optimize other logic.
!There are mods that may slightly affect vanilla seed parity. If it is important for you to keep vanilla world unchanged and you want to + will be playing with vanilla generation - you will need to remove this mod, and structure_layout_optimizer.jsonc config file.
(things may change, so it's best to double-check what is written on the official mod pages)
Some configs have been changed.
Configs I recommend checking or adjusting
C2ME.
Recipe Essentials (can disable the recipe book).
NeoForge itself.
