🔥 FramePacer - Stable FPS without jitters! 🔥

Ever noticed stuttering when using an FPS cap?

You're not imagining it — those are frame time jitters!

FramePacer aims to fix this!

📊 Benchmarks 📊

The vanilla frame limiter in versions <=1.21.11 puts the thread to sleep, but due to OS timer resolution limitations, this introduces timing inaccuracies, resulting in unstable frame times.

vanilla_1.21.11_test

#frame drops are visible here.

In versions >=26.1, developers attempted to fix the limiter by switching to a hybrid approach.

However, the vanilla implementation introduces excessive architectural complexity, which can still lead to timing imprecision.

vanilla_26.2_test

#Frame drops became less visible, but it still not disappear on my test.

FramePacer uses a lightweight, optimized hybrid sleep algorithm to improve frame limiting precision.

mod_26.2_test

#Testing on 26.2 + FramePacer shows smoother framerate.

❓ Benchmark Notes ❓

  • Tests were conducted using Fabric + Sodium. Sodium does not alter frame-limiting methods and eliminates game-specific variables.

  • Tests were performed in an empty world to isolate the limiter's performance from gameplay overhead.

👑 Features & Highlights 👑

  • Size <5 KB.

  • Zero dependencies.

  • MIT License. Feel free to include FramePacer in any modpack.

  • Compatible with other mods (except similar mods).

  • Multi-version and multiloader support

  • Precision frame pacing.

❗ Important Notes ❗

FramePacer does not increase FPS! it improves FPS cap stability.

Do not use vsync and fps cap together. Vanilla vsync+fps cap overwrite each other and make unstable fps.

🌲 Supported Versions 🌲

  • Fabric 1.14 - 26.3

  • Quilt 1.14.4 - 26.3

  • NeoForge 1.20.1 - 26.3

  • Forge 1.15 - 26.3
