If you could send my thanks to the Chaos Physics Team, they have really come a long way in a short time.
I had to convert from 4.27Plus and was really dreading it because the game is heavy physics based and I had tested Chaos in 5.0 and it was new, slow and had some issues. Now in 5.4 I had to upgrade and it went so much smoother than I thought.
I did spend about 2 weeks fine tuning all the constraints but am happy with Chaos and proud of the engineers at Epic. Here is a video of a 100% physics motorcycle and rider running at solid graphics at 60 FPS on PS4 and physics running at 120FPS:
