Particular + Echo Taking Way Too Long to Render

Hey everyone,

I’m running into a pretty time consuming rendering issue and wanted to ask if anyone has dealt with something similar before.

I have an particle effect that uses Trapcode Particular combined with Echo to create particle trails. The look is perfect, but the render times are absolutely insane. For example 2 minute 16 seconds of a footage takes about whooping 3 hours to render sometimes even longer.

Here it is basically how it looks like:

Particle trails created by increasing Wind in Particular, and Echo is what makes them dotted like this.

I tried pre-rendering the particles first and then applying Echo, but it doesn’t produce the same result. I also tested alternatives like CC Time Blend etc. but none of them matched Echo’s look either.

Are there any tricks to make Echo faster with particle systems? or is there any plugin that behaves like Echo but renders faster?

For the record I’ve also tested the same project on friends systems (i have GTX 1650 Ti, they have RTX 3060 Ti and RTX 4060) and the render times were basically same, painfully slow.

Any advice or alternative workflows would be greatly appreciated!
