I'll leave some details here for posterity.

Details of the scene:
- I have a composite texture with 3 sub materials
- Each sub material has 2/3 chaos nodes for various maps
- I am using ...

Thanks for this update. Unfortunately I am still experiencing extreme input and UI lag when using chaos nodes in certain situations. The log is empty. I will work on trying to reproduce a scene I can share today.
