tntOptimizer
We all love exploding vilagers but we hate the lag it gives. This mod fixes the tnt lag mainly serversided and a bit on the client
Quick answer
Which tntOptimizer release should I use?
tntOptimizer 1.6 targets 26.1.2, 26.2 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. All 1 required mods have matching files.
Where it goes
Is tntOptimizer required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does tntOptimizer 1.6 need?
1.6. Change the file and its required mods may change too.
Install Fabric API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it

About this project
What does tntOptimizer add?
What does this mod do?
This mod improves TNT performance
The goal is to reduce lag while keeping TNT behavior as close to vanilla as possible.
How close to vanilla is it?
I tried to keep the mod as close to vanilla as possible. However, because the number of active TNT entities is limited, there is a small chance that some edge cases will behave slightly differently.
How does it work
It works by limiting the amount of tnt rendered client side to 75
Also limis the amount of explosion particles the client renders to 100
On the server side of the mod we limit more things:
- we limit how much tnt is active at once
- we limit how much tnt explodes at the same tick
- we merge close tnt into 1 to waste less calculations
- we cache explotion calculations so we do less calculations
Will it break my TNT cannons?
Most TNT cannons should continue to work normally.
However, if your cannon relies on more than 250 TNT entities being active at the same time, it may not function correctly.
So yes, this will almost certainly break an orbital strike cannon.
