Both these have the same meaning. Checkerboarded 1800p just means 3200x1800 but with half resolution on the horizontal axis (so, 1600x1800) which gets reconstructed to a final 3200x1800 output. This output is always upscaled to 4k regardless of what the input resolution was.
There tends to be a lot of confusion over this but 'checkerboarding 1800p to 2160p' is a contradiction. It's just 'checkerboarded 1800p' which makes it all the more strange why the game looks so poor in performance mode. Unless it's simply the wrong number or possibly just a bug that needs fixing.
How so? 1800p that's achieved via checkerboarding will inherently have a lower native resolution base than a native 1800p rendering that is checkerboarded to 4k.
