Caustics produce more noise

[kakikami]

Hi, i have some issues with noise when i use caustics.
Anyone know how to reduce noise effectively or tricks when caustics on?

Normally i used noise limit 5.0 is enough to looks clean if without caustics turn on.

I am using corona 7.1, 3ds Max 2022.
 
I attached some settings and render preview.

If you're not against using daily builds, i would suggest to try latest v8 build - it has caustics include/exclude list, so you could try to limit number of objects that receive caustics and see if that helps with the noise. Just don't forget to make copy of your scene first, in case you would want to go back to v7.
