About this project
What does Hypertale add?
Hypertale: Optimize your server even before it start!

⚠️ Note: Hypertale may restart the server during initial installation ⚠️
- This is only to install HypertaleInit, which is bundled inside Hypertale
- Just restart the server and you will have Hypertale properly installed
- You might need to add
--accept-early-pluginsargument on some hosts
Please do not forget to get the Hypertale: Libraries mod when downloading from CurseForge, this is not an optional dependency on the CurseForge version of Hypertale.
Hypertale is a mod that automatically optimizes the server even before it starts!
Memory pressure is how much memory is allocated per second.
When high, this makes the java garbage collector slow the server down a lot!
Spark was used extensively a lot to help with performance profiling.
Hypertale is compatible with existing performance mods for Hytale!
Hypertale also can also load Hyxin mods on it's own!
