Denoising node strategy

Hi, i have a question, is it better to render for example 4K 128 Samples or 2K 512 and denoise.
I mean is the denoising better with higher samples or higher spacial information.

Thanks

The first is better + denoise :wink:

I prefer to downsample. Edges and internal clarity are better preserved in denoise, and I get to apply a little bit of sharpen during downsample to restore some of the sharpness lost to internal filtering.

Thank you guys. I also just noticed that especially albedo profits off of higher res. less artefacts.
