StableCap Pacer

StableCap Pacer is a client-side performance utility that improves capped FPS smoothness by using a high-precision frame pacer. It helps reduce frame-time jitter and micro-stutter when you play with an FPS limit.

This mod works with any FPS cap — 120 is just the default. You can set it to whatever you want (60 / 90 / 120 / 144 / 165 / 240, etc.).

How to use

• Set Minecraft Video Settings → Max Framerate to Unlimited (or 260) so you don’t double-limit.

• Launch once, then edit: config/stablecap-client.toml

  • Change targetFps = 120 to your preferred cap.

Recommended for smoother pacing
For the most stable feel, set the target slightly below your monitor refresh rate:

• 120 Hz → 117–119

• 144 Hz → 141–143

• 165 Hz → 162–164

• 240 Hz → 237–239

Notes

• Client-side only (no server install needed).

• StableCap improves frame pacing, not maximum FPS. It won’t “force” extra FPS if the game is limited by CPU stalls, chunk updates, or heavy rendering — it just makes capped FPS feel steadier when the system can keep up.
