Greetings Everyone!
Could i please get some assistance on this particular issue i am having for a scene, if you see attached... i have tried lighting / denoiser / filters the works - cant seem to get rid of these damn fuzzy dots..

I think there is glass with refraction. It is one of most difficult algorithm. Another "noisy" alghoritm is specular with high rughtness.
I do not know light setting and most parts of your scene, then I do not know if mysetting help, anyway they are good start to adjust it.
First try to replace glass shader with something easier for your CPU (clear renders are worse, but noises are less natural then not correct angle of light bounce). Refraction=0 with opacity=10-20%. Glossy weight=0, top coat=20, roughtness=0.2-0.3, type custom curve, top coat curve 0 = 0.2, anisotropy = 1, rotation 0.2.
Try spot render of noised area. If you do not like result you can set anisotropy = 0. Custom curve=0.1 and of course increase/decrease opacity. To obtain "frame effect" darker edge of glass set glossy=1 but color black. Good luck.
and... This is wrong thread
