I'm trying how to make good looking glass caustics in Cycles, without building a power plant to fuel the rendering rig.
How many passes for the same render? 2048 is very noisy. I put 50 000 to have something worst than your pic. Did you use a denoiser?
All I can see is you simply used the built-in glass shader.
