nullie's FPS Benchmark

The benchmark runs on the client, and the server needs the mod too, so it is listed as client and server. A player opens the settings menu and presses the Start FPS test button. The test measures real-world performance rather than a synthetic workload, so results reflect how the game renders in normal play. Each run produces two report files: a human-readable HTML page and a machine-readable JSON file, which makes it possible to compare results across Minecraft versions, hardware and settings.

The author notes that other mods which change world generation can break real-world benchmarking, because the test depends on a fixed seed. Shaders are used when taking the test screenshots, so the captures match the Complementary Reimagined look. A Search button opens the reports folder directly from the game. The source code is open source under the GNU General Public License v3.0 only, and the project keeps a public issue tracker. Files are published for NeoForge only, covering 1.20.6 – 26.2 across 13 release versions, and the latest file is 0.0.1 for 26.2.
