James Survival

James - Survival, Smooth, Server

A large NeoForge survival pack for Minecraft 1.21.1, built as the permanent home of a small private server with around 20 players (about 10 online at the same time). It is not a kitchen-sink dump: every mod has a job, and the numbers in this description were measured on the machine that actually runs it, not copied from someone else's spreadsheet.

What you get

344 mods, 33,303 recipes, one coherent progression from first wooden pickaxe to endgame automation.

• KubeJS ready for your own recipes and tweaks, with 186 datapack files already fixing broken loot tables, tags and recipes from other mods

Performance - measured, not guessed

The pack ships start values that suit weak hardware, delivered by Default Options: render distance 16, simulation distance 8, fast graphics, 2 mipmap levels. Every player can change these in-game afterwards; they are start values, not locks, and they never overwrite the settings of a player who already has the pack installed.

Server measurements (the real world, 392 MB, 48,165 chunks):

• 0.39 ms per tick with no extra chunks loaded, 20.00 TPS
• 5.7 ms per 1,000 permanently loaded chunks - linear across 512, 1,024 and 1,536 chunks
• The 20 TPS limit is reached at roughly 8,500 permanently loaded chunks
• Chunk generation: 7.8 to 14.6 chunks per second while TPS stays at 20.000
• Storage cost: 20 to 28 KB per generated chunk
• Fresh world start: "Done" after 16.3 seconds with 304 mods on the test server
• Log after a full start: 6 error lines, all from known bugs inside other people's mods (Integrated API map decorations, one Patchouli book, one Pam's HarvestCraft tag, HammerLib, one README inside a datapack), zero errors from the pack itself

Optimisation mods included: Sodium, Iris, Lithium, FerriteCore, ModernFix, ScalableLux, BadOptimizations, ImmediatelyFast, EntityCulling, MoreCulling, Dynamic FPS, Clumps, alltheleaks, FastLeafDecay, FastWorkbench, FastFurnace, Optimized Block Entities, Noisium, and Prism + Iceberg for tooltips. Deliberately left out: mods that fight Lithium (Performant, Canary) and mods that add work instead of removing it.

What makes it different

• The interface is rebuilt by a bundled resource pack (James-Optik): own main menu artwork, logo, panorama, 30 splash texts, German menu translations, its own click sounds and an 85 second login theme. It ships inside the pack, so it works out of the box.
• Item tooltips are reworked (James-Tooltips) with clear names, durability lines and descriptions.
• 186 datapack files in kubejs/data repair things other mods ship broken: unreadable loot tables, the replaceable block tag, missing advancement roots, impossible recipe patterns, structure spawner lists pointing at mods that are not installed.
• Titans from my own mods: Titanwood (giant trees, floating islands, giant mushrooms, giant bamboo, palm beaches) and a small controls mod for the server keybinds.

Server package

A ready-made server build is published as a separate file. It contains the 304 server-side mods, the same configs, the same kubejs fixes and a prepared server.properties set up for 20 players (view distance 10, simulation distance 8). Java 21 is required, 8 GB RAM is the practical minimum, 12 to 16 GB is comfortable for 20 players.

Requirements

• Minecraft 1.21.1, NeoForge 21.1.265 (bundled with the pack)
• Java 21 (the CurseForge and Modrinth launchers handle this automatically)
• 8 GB RAM allocated to the game for a smooth experience, 6 GB is the absolute minimum
• An SSD. The world is 392 MB after weeks of play and grows by 20 to 28 KB per new chunk.

Credits

Every mod belongs to its author and is downloaded from CurseForge - nothing is reuploaded, nothing is modified. Configs, resource packs, the KubeJS fixes and the two own mods are mine. Thanks to every mod author whose work makes a pack like this possible.
