🔥 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.
#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.
#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.
#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.
