I have noise on white and metal surfaces.  
It is very noticeable in dark areas and when seen from afar.

  
How can I reduce the noise (or make it disappear completely)?

Thank you so much!!

I found that the frame rate greatly influences the noise:

t.MaxFPS 30 → more noise  
t.MaxFPS 120 → less noise

Anyway I would like to have not noise at 30 FPS.  
Because I always work at 30 FPS. This way I spend less energy.

This does work…

But the performance is horrible…

A better solution is welcome.

Thank you so much!!

Ok… in my case i think this is the best solution (for now)  
No noise and good performance!!

Simply use “NONE” as the global illumination method.

The downside is that some shadows look very strange.

A better solution is welcome!!  
Thank you so much!!

This fixed everything:  
Noise, shadows and performance.

To decrease noise, use soundproofing substances like acoustic panels, rugs, and curtains; seal gaps around home windows and doors; and think about white noise machines or noise-cancelling headphones.
