AMFP at 360hz, nice :)

This one was a copy paste moslty of the TDD fix, but it still took a while to test everything and make it work.

The approach is the same as all the other fixes, Responsive Interpolation Layer (RIL):

• decouple game logic from rendering (this could simply mean multiple display, or 'presentation' frames for each real logic frame)

• interpolate all world positions, rotations & animations in non-logic frames towards the next logic frame

• add a per-frame mouse delta override to restore mouse input latency to 240hz/whateverhz levels

Nothing much to say especially compared to the TDD post.
