The PS4 Pro when outputting at 2160p renders at a resolution of 3200x1800 using what appears to be a form of checkerboard rendering. When outputting at 1080p the PS4 Pro version downsamples from a native resolution of 2240x1260 to 1920x1080. The PS4 Pro when outputting at 2160p has noticeably worse depth of field than the PS4 Pro outputting at 1080p.
The Xbox One X version seems to render at a resolution of 3840x2160 and also appears to be using a form of Checkerboard Rendering. There does appear to be differences between the two implementations with the Xbox One X version showing more artifacts, but they shouldn't be intrusive on either platform.
