Glass reflection noise

Hi Team - how can I remove noise on glass material. Even if I have 0% roughness it still shows some noise specs. I does not happen on all projects. I think it might be that there is not enough GI bouncing around to remove this. Any ideas on how to finding a way around it.

Thank you.

Hi there,

Could you provide with screenshot of it?
Probably you could try to make some adjustment on Normal parameter,

Thank you
