Question VFX lag on slow movements

Hey everyone! Sounds like a stupid question but I'm sitting on this one for hours. Consider this *very* basic vfx, which slowly moves a bunch of white quads on the y axis.



Their movement is not smooth for me as you can see in this video: https://nc.artcom.de/index.php/s/CjRHfB5rPDNWogd

Do I need to factor in delta time in the vfx or is this sort of "micro-jitter" always to be expected for very slow movements?

 

You don't need to set velocity every update, you can just initialize it with some velocity and default integration during update will move it for you.

About the actual problem - I am pretty sure this is caused by different update rate. By default vfx uses fixed delta time, so what you see is the same kind of problem as moving rigidbody without interpolation. It's possible to change this behaviour, if you click the graph asset you can find checkboxes about delta in the inspector.

 

That did something! It definitely improved things, but it still does not feel 100% smooth..

There are still these micro jitters in there that are really noticeable in slow animations. Hope the recording captures it

 

In this case I have no other idea other than the one you mentioned already, it might be just that precision flicker between pixels. Maybe you should try some custom integration with rounding or with different delta?
