How to make a stream with particles?

I would like to make a water stream like one of a super soaker or a firefighter water gun. It should shoot from the player FPV pretty far away, like 7000 units.
Now the main problem I have is that fast particles always result in a non constant stream no matter how high I set the particles count and the particles get this weird position increments effect. But it needs to be fast because such streams are very fast and I’m using hit tracing with it.

Maybe I’m just doing it all wrong?

Furthermore it should have some acceleration downwards so the stream shoots a bit in a ark. In any case there needs to be speed to it so you can actually see it shooting when you start it and because of speed it should look like it drags a bit behind. So using just a stream mesh instead of particles is not a option.

Did you try changing your velocity to a uniform distribution, say 2000 and 1000? right now all of your sprites are moving at a constant 2k value, which means they will emit at intervals over time (number of particles per second for spawnRate) so you get spacing between particles if they are small enough.

You want to be careful not to spawn too many particles as your memory usage goes up…

That in the gif is uniform. I had found a workaround, my answer here covers it: https://answers.unrealengine.com/questions/260096/making-a-stream-of-particles-doesnt-work.html
