I don't think this is how it works. What you are referring to is similar to field rendering which is what the early PS2 games used(also why alot of early PS2 games looked jagged). It renders two alternating fields of scanlines(odd and even) per frame and combining the two to create a smooth motion. This allowed developers to render games internally at half the resolution(say 240i/p) and output at 480i/p(the standard back then) with enhanced frame rates.

Checkerboard rendering is this:
It essentially averages the neighboring two pixels(diagonal from eachother) and reconstructs one parallel to both. I think this is the basis of it, although I have read it reconstructs 2 pixels for every 2 native pixels which makes sense as 4K contains 4 times the amount of pixels as 1080P(1080P is 1920 by 1080 whilst 4K is 3840 by 2160). There are no alternating pixels popping in or out like with field rendering. So you fill in the black empty areas with reconstructed pixels, giving you 4 times(as 4K/2160P has 4 times the amount of pixels as 1080P) the amount of pixels at much less expense to the GPU compared to native 4K

Yes, that's what I meant by interpolate the non rendered squares using the rendered squares. But I also thought I had read something about temporal interpolation in the Eurogamer article. In static scenes the info from the previous frame can also be used.
Btw I doubt that Scorpio can do native 4K when the same game uses checkerboard 4K on ps4 pro. The ratio between pro and scorpio is about the same as between ps4 and One. Either the pro version will run smoother with more effects or the scorpio version will need to upscale somewhere too. The equivalent checkerboard 1080 is only 72% of 900p, or by the same ratio Checkerboard 4K and about 3264x1836 on Scorpio.

Ahh understood :)
Native 4K is difficult, especially at 6TF. I don't think we will be seeing The Witcher III at a solid native 2160P on Scorpio. So if we had the same game on Pro and Scorpio running on checkerboard 4K(Pro) then the Scorpio version would theoretically be at maximum 3264x1836 due to the power difference ratio?
