FFXIV's bone physics consist of wind and bounce physics. These apply to the character's hair, clothes and other body parts. However, some aspects appear broken on high framerates, especially those above 60 FPS. Notably bouncing happens so quickly that it's practically non-existent, and wind effects tend to appear jittery.
This plugin fixes this bug by locking updates to 60 FPS, and is based on Kirrana's plugin to be more opinionated with less options.
This system was never designed to be locked to 60, so clipping will happen. If this bothers you (for example, it will easily ruin recordings and certain cutscenes) avoid this plugin. Some bones are always updated at the current frame rate, such as hair bangs to alleviate clipping.
This plugin is currently available in my personal Dalamud repository.
I initially thought the physics was meant to run at 30 FPS, because of PS3/PS4 console performance. However, the "bounce rate" applied to bones is "60.0" (float in BoneSimulator at offset 0x54) and the physics generally look good at 60 FPS even when the game is running >200 FPS. It also avoids other issues like hair bangs clipping through the head because character positions are updated too infrequently.
The plugin is extremely simple, and basically a pared down version of Kirrana's. If your current FPS is above 60, it will begin spreading out physics updates - basically locking it to a fixed rate. When the current FPS is below 60, the plugin effectively does nothing.
BoneSimulator::Update is fundamentally broken. It's also amazing how it's stayed broken for this long. Don't expect to be able to fudge the numbers to make it work without skipping, it's simply impossible.
Framework, but it's not possible due to the bone simulator jobs running in parallel with other animation jobs. Basically, you'll end up with statically animated objects like flags running at a different speed tshan everything else.Thanks to Kirrana and the contributors for the original plugin.
