⚠️IMPORTANT⚠️
This mod requires Fabric API.
Mod Description
Memory Usage Display is a client-sided only Minecraft mod, for the Fabric Loader, that allows users to view their game memory usage, via Minecraft's action bar. For example, the action bar text would look like this: "🟩 - 2.0/10.0 GB (20%)". The square's (like in example display text) color, changes based on the amount of RAM used of the total.
The whole mod is toggleable with this command that the mod adds: /toggleramdisplay.
For a visual of the mod, please visit this mod's Gallery Tab.
Why Download?
While the vanilla debug display allows you to see your memory usage, this mod's way to display usage is direct, allowing you to simply see it right above your hotbar, instead of having to look through all of the text to find it.
