10,000,000 photons really needed?

to get any caustics to appear i have to have the photon light close, maxed at 10 brightness, and 10million photons.
is there something i need to change in yafray to make this stuff more sensitive?
my glass seems fine, it’s the same glass i’ve been using forever and i’ve never seemed to have this problem.

Maybe set maxdistance in photon light properties to 200 or something?

turn up the blur to about .05, turn the depth to about 5, then depending on what you’re doing you shouldn’t need that many photons, maybe around 10,000-30,000
