Bloom Benchmark

Bloom Benchmark is a lightweight, completely client-side Fabric mod that runs a consistent in-game performance test. Instead of relying on rough estimates or hardware specifications, it measures real Minecraft performance inside a standardized, fixed-seed world.

Features

• Measures your average FPS
• Calculates your 1% low FPS to reveal stutters
• Tracks average and 95th-percentile frame times
• Monitors peak Java memory usage
• Uses a fixed seed and automatic camera movement for more comparable results
• Includes a 15-second warm-up followed by a 60-second measurement
• Displays results directly inside Minecraft
• Saves a detailed report locally
• Includes a convenient Run Again option

How to use it

1. • Install Bloom Benchmark alongside Fabric API.
2. • Launch Minecraft.
3. • Click Bloom Benchmark on the title screen.
4. • Let the automated test finish.
5. • Review your results inside Minecraft.

The mod creates a dedicated local benchmark world, controls the camera automatically, and handles the complete test without requiring any in-game setup.

Privacy and compatibility

Bloom Benchmark is entirely client-side and does not need to be installed on a server. Benchmark results and hardware measurements remain on your computer—they are never uploaded or shared.

Bloom Benchmark also powers the real-world performance testing behind Bloom Client AutoTune, helping Bloom Client select settings based on measured performance instead of generic recommendations.
