So I've been playing around with the denoiser this morning and either I'm not using it correctly, my machine isn't powerful enough to notice a difference or it doesn't do what it's supposed to be doing for me. I have a Dell Precision 7710, 16GB RAM w/ Nvidia Quadro M3000M (4gb DDR5 VRAM).
I've tested with the denoiser on and off both in the viewport and with producing renders and I'm not seeing the 10x faster speed. Attached a couple examples below. Render settings were as follows:
No Denoiser (3 mins 18 seconds)
With Denoiser (3 mins 6 seconds) -12 secs!!
It seems the images are identical or at least I can't spot the difference and there are still artifacts in the image, particularly around the glass doors. Am I doing something wrong or misunderstanding what the tool is supposed to do?
