I am using Blender for daily work on 2540x1440 external display. I usually work in full screen layout and sometimes i want to preview scene in cycles. Problem is that working area is over 2000px wide and it totaly waste of time to wait for each sampling iteration. My question is: Is there any kind of method to decrease the resolution on preview. Something like quality switcher in After Effects (25%,50% full etc.)
For preview purposes it could reduce the pixels like 2x 4x or 8 times. This way instead of rendering full resolution the "pixels" could be bigger allowing user to preview faster.
Thanks For Your reply!
