Ok, so this is getting to crux of what I'm asking. I was under the impression that the Series S is powerful enough to give the best possible performance at 1080p, and that the extra TFLOPS, RAM, processing speed, etc of the Series X is wasted in 1080p. So if a game is designed to run at 900p/30 it can potentially run at 1080p/60 on the Series X? Is that possible? I thought if a game was designed for a specific resolution/fps it can't go any faster no matter how powerful the console.
Well it depends...
A developer can hard code a game to work only at certain FPS and resolution (thus why some games when ported need to have that either unlocked or won`t see improvement on framerate and what not).
And yes a game could be made under fullHD on Series S (I doubt, but not impossible).
Also it is possible that some devs will allow us to have several options so let`s say you have Series X but don`t have 4k, so you can for example decide for higher quality RTX or Ultra effects like in PC.
