After some tests with different render sizes and settings, amount of samples etc. i am really impressed with the low amount of samples you can get away with, if you have enough pixels to work with for the Denoiser.
I rendered the image in 5760x3240 with the lowest amount of samples(32) for Cache Friendly Rendering.
Then i did some slight post production in RawTherapee and scaled the image down to 4k resolution.
The rendering just took me 8min 57sec on a RTX2080ti and a Ryzen 1700x
I will never again spend thousands of samples on a 1k image i think

nice tip.. thanks for sharing
Re: Rendering in High Resolution for good Denoising
Nice trick, there is another approach too, when I want to create a big image with good quality. first, I'll cache the light with a small size image and use that cache to render a huge size image without actually light calculation. this trick will give you better results and also it is much faster.

Wow, that's a very cool trick. Must try, what about animation?
Re: Rendering in High Resolution for good Denoising
For a Blender and LuxCore newbie could you expand on how to obtain and use that cache?
Cheers.
Re: Rendering in High Resolution for good Denoising
I'm not a blender user but like every other renderer and software, you should be able to save light and sample cache and reuse it later.
I think you can do that in the render setting and with the cache option. Then run one frame rendering to create the cache file then disabled the "Compute & Overwrite" flag, Now you will be able to render with saved cache.
