Stable FPS
Minecraft mod to fix long-standing FPS stability issues.
About this Mod
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- Minecraft 26.1 and above: Fix dropping by 1 FPS due to using out-of-date information.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 toglfwPollInputs().

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.

Stable FPS server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.
Is Stable FPS compatible with fabric and forge and neoforge?
Stable FPS officially supports fabric, forge, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Stable FPS – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Stable FPS consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
