Hi guys,
If you render an image at 4x the size, eg you will have 16x as much pixels (4x4),
you will, with 1 pixel sample, have the same noise level as 16 pixelsamples in the original resolution.
So it won't take 16x as long to render.
Rendertime is the same, you just need to render 16x less pixelsamples, then downscale and you'll have the same noise level, but a much nicer result.
