Frequently asked questions

How do I turn on the memory usage display in the title bar?
The mod shows memory usage in the window title automatically once it's installed and the game is running. If you don't see it, make sure the mod is actually loaded for your current profile and that no other mod is overwriting the window title.
What do the numbers in the title bar actually mean?
The readout shows how much memory Minecraft is currently using compared to the maximum memory allocated to the game. The used value rises and falls as the game loads chunks, entities, and assets, while the max value stays fixed unless you change your allocated RAM.
Why does the memory number keep going up and down?
That's normal — Java's garbage collector frees unused memory periodically, so the used figure climbs as you play and drops when collection runs. Steady sawtooth patterns are healthy; a number that only climbs and never drops is the one to worry about.
Does this mod use extra RAM or hurt my FPS?
The mod only reads memory statistics and updates the window title, so its own footprint is negligible. Any FPS impact is effectively zero compared to the memory reporting itself.
