Motion Blur / Redshift - TyMesher Slow Down

[tyFlow]

This is my experience:

1) I open your file with Max 2024, tyFlow v1.106, RS 3.5.21
2) Delete the tyMesher
3) Unhide the tyFlow
4) Enable particle interface on the tyFlow
5) Move to frame 70
6) Render

Attached is the alpha channel of the result.
