Hello dear blenderers , i was reading an old article about speeding up cycles render and saw a comment that put me in thoughts.
comment was:
render in a higher resolution blur it a bit (if you want) and make it smaller afterwards. I usually use the doubled resolution than I need. And lower the samples of course.
Example: of one of my renders
1920x1080: 40 Samples 45min of rendertime
3840x2160: 8 Samples 10min of rendertime
at the moment i cant render to test myself, but would like to hear your opinions on the end result,which would be the issues if used that way?
Cheers! :o
