Description

Minecraft mod to fix long-standing FPS stability issues.

1) Implement proper frame pacing when FPS target is limited (due to user setting or being inside a menu):

  • Minecraft 1.21.11 and below: Allow FPS to actually reach the target instead of randomly being 5-20 FPS lower.
  • Minecraft 26.1 and above: Fix dropping by 1 FPS due to using out-of-date information.

2) Get inputs on a separate thread to fix FPS dropping by 2-3x when moving the mouse (especially on high polling rate mice on Windows) due to glfwPollInputs().

Comparison:

- Vanilla: https://www.youtube.com/watch?v=OW-tKVvHjY4
- Stable FPS: https://www.youtube.com/watch?v=lk8H2A76Nss

NOTE: You may experience graphical glitches when starting the game or resizing the window - this is intentional, as it would require a ton of work to fix and I want to keep the changes to a minimum to be compatible with other mods.

Compatible with Sodium.
For a version compatible with Ixeris, see Lite FPS.

Recommended settings:
- Fullscreen: ON (due to Minecraft using Hardware: Legacy Flip on Windows)
- VSync: ON (to not waste time rendering frames that won't be shown)
- In Vanilla: Max Framerate: Unlimited (due to Vanilla fps limiter being broken)
- With Stable FPS: Max Framerate: any
NOTE: Some versions of Minecraft have a slow renderer, so you may need to limit your fps further on those.
