You have to process everything at a higher resolution (4k+ ) and you will be able to get rid of the noise without losing detail and have a crisp clear render. Start rendering the scene at 2,400 pixels wide at least... then enhance it to 4,800 pixels wide... now remove the noise and blur then rescale it back to 2,400 .... if you must lol

"Sure – but bigger render size means longer render time (double size, double time). That's what you avoid with a denoizer.

But let stop discussing this – maybe the OP has other interesting things to publish."

But as Adp001 say you still have to render more. With the denoiser you can render fairly noise images and still get something fairly good out of it. But since the program works externally, you could probably combine both method and might give you a good or even better result, worth testing :)

Personally I have to say that it does a good job in removing noise, obviously it would be nice if there were some setting for how aggressive it is.
