Stable FPS

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• Minecraft 26.1 and above: Fix dropping by 1 FPS due to using out-of-date information. 2] Get inputs on a separate thread to fix FPS dropping by 2-3x when moving the mouse (especially on high polling rate mice on Windows) due to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().

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.
