Minecraft 1.21: Potato Certified

Who said Minecraft needed a 64-bit CPU starting from version 24w14a? Microsoft? Pssssssssh.

Lies.

This here's a Minecraft 1.21 optimization modpack battle-hardened and tested against 2006-era PC hardware! You may encounter some stuttering in singleplayer, but it's nothing unmanageable without a shield and some armor.

Tested against the following specs:

• 32-bit Intel Core Duo T2700 @ 2.3GHz
• Nvidia GeForce 8800GTX
• 4GB system RAM (up to 1024MB allocated to Minecraft, suitable for 32-bit systems! Still playable on 512MB of allocated RAM.)

Known issues:

• Singleplayer performance is still somewhat stuttery due to the need to balance client-side rendering with integrated server performance. It is possible to get a smooth stutter-free client-side experience, but at the cost of very low TPS in singleplayer worlds.

The above issue can be somewhat mitigated by increasing the allocated memory to 1024MB, though YMMV and it is recommended that you try to hand-configure the installed mods to better fit your system's needs.
