Have studied this lengthy documentation and screen percentage is starting to make more sense however I have a question not really covered.
act independently and together to either upsample (better performance) or super-downsample (better quality) your scene.
But what are some optimal setting combinations for both up and downsampling if targeting Windows desktop or Xbox?
Also both only work in PIE mode or or standalone binaries.
Is there any way ScreenPercentage can work in the editor Viewport when NOT in PIE mode?
