So you know that a console is 2x faster than a pc with the same hardware because of optimisation, if you are creating a game for pc you have to look for alot of cpus and graphic cards!
On a Console you can put every power you have to make a game.
I think the games will run like this:
XB0 /XBO S:
720p 30/60 fps < medium to high details
900p 30/60 fps < medium to high details
1080p 30/60 fps < medium to high details
scaled to 1080p
XBO Scorpio:
1080p 60 fps < Ultra details
1440p 30/60 fps < high to ultra details
4k 30/60 fps < high to ultra details
scaled to 4k, dynamics resolutions possible.
