TNTmark

A Fabric mod for Minecraft 26.x that benchmarks your CPU using TNT explosions. It spawns increasing waves of TNT, measures your TPS under load, and calculates a score — so you can compare your system's performance against others.

Features

• Escalating TNT waves that progressively stress your CPU.
• TPS measurement under load to see how your system holds up.
• Comparable score you can put up against other setups.
• Multiple runs per wave for more accurate, reliable results.
• Automatic game rule adjustments so the benchmark runs cleanly — restored to your original settings when it finishes.
• Timestamped result files saved to disk for easy comparison over time.

Usage

/tntmark start
/tntmark stop

The benchmark runs on its own from there: every wave doubles the TNT count until your TPS drops below 15, then the score is printed in chat and written to disk. You can cancel at any point with /tntmark stop.

The TNT is ignited 250 blocks up and floats in place, so your world takes no blast damage.

On a server, /tntmark requires OP (level 2). In singleplayer it always works for the host, with or without cheats enabled.

Results

Results land in tntmark-results/ inside your game directory, one timestamped file per run. The TNTmark Ergebnisse button in the pause menu opens that folder.

Requirements

• Fabric Loader & Fabric API
• Java 25
