Put A Plug In It Mod FAQ
10 questions players actually ask, answered.
How do I know if Put A Plug In It is actually working?
There's no in-game menu or command to toggle; the fixes run automatically on load. Watch for smoother frame times during long play sessions and less RAM creep in your launcher's memory graph, especially after exploring or fighting Drowned.
Do I need to configure anything after installing it?
No. The mod is designed to work out of the box with sensible defaults, so you can just drop it in and play. If you use a config file, only touch it if another mod's docs tell you to.
Why does my RAM still climb even with this mod installed?
Java's garbage collector doesn't return memory to the OS immediately, so the graph rising isn't necessarily a leak. What matters is whether it drops back down after a GC cycle and whether you still get stuttering or crashes.
Can I use this alongside other memory or optimization mods?
Yes, it's built to integrate and adapt features from other memory-leak and optimization mods rather than fight them. If two mods patch the same leak, you may see a duplicate-fix warning in the log, which is usually harmless.
How does it fix the Drowned memory leak?
It cleans up navigation data that Drowned accumulate when they pathfind, which normally sticks around after the mob is gone. You'll notice it most on servers with lots of ocean or drowned-heavy areas.
What is the entity brain-memory cleanup trio?
It's three related cleanups that clear stale brain memory entries from mobs that no longer need them. This prevents mobs with complex AI from slowly bloating your memory over long sessions.
Does this help with server lag or just client-side memory?
Both. The leak fixes and cache sharing reduce server-side memory pressure, which helps TPS, while the client-side fixes like screenshot buffer cleanup and hit-result reset reduce client RAM use.
What does the TagKey weak intern pool do?
It stops duplicate TagKey instances from piling up in memory by sharing them through a weak pool. You don't interact with it directly; it just reduces overhead from tag-heavy modpacks.
Will this mod break my existing world or modpack?
No, it doesn't add blocks, items, or world data, so it's safe to add or remove. Removing it mid-world is fine because it only changes runtime behavior, not saved content.
The mod isn't helping my stuttering — what should I check?
Make sure you're not also running another mod that patches the same leaks, since conflicts can cancel fixes. Also check that your allocated RAM isn't too low or too high, as both cause stutter independent of leaks.
