not currently, but it’s really easy to calculate.
it may find it’s way as an attribute in a future release:

well, velocity is a vector, so perhaps you want the magnitude of the velocity (speed).

ouh yes,, more precise, now you see why i ask for the attribute.. ;)

even do if i change the qmetro from 5 to 20 in your patch im getting also glitching values, but i find (dont ask how) that changing fixedtimestep to 50 or maxsubsteps to 2 fix the issue. :-?

so seems important to match the overall fps with those settings… ?

thank you very much!
