Disclaimer

Versions in Alpha (1.20) (v1.2.2) are only in alpha because its very experimental and i plan on fixing stuff as well as in the future adding alternatives to some mods you can't find as originals

Versions in Beta (1.20.6) (v1.2.4) + (1.3.0) are those that are technically a release but have random stuff that needs fixing (for example the bug where you frequently crash in singleplayer worlds and idk how to fix that yet)

Releases are versions that have been tested and found to work well and no crashes are pretty much garanteed

How the modpack is tested

Tests:

  • Singleplayer compatibility
  • Multiplayer compatibility
  • FPS (Tested on servers with high player counts like Hypixel)

My system:

  • AMD Ryzen 5500 series
  • Nvidia rtx 3060 12GB
  • 16GB DDR4 RAM 3200mz
  • 1080p@75 hz monitor
  • 1440p@155 hz monitor

Quick Note

Use at least 4-5GB RAM, 6GB recommended, especially if using VR

Side note

As newer versions of the game come out you can expect some delay in me making compat for those versions because the mod devs already take a couple weeks to port their mods to newest version but as soon as they come out, this modpack will be updated to 1.21.2-1.21.3 / 1.21.4
