Probably a lot in different respective areas like RT, shadows, detail. And, lumen like you said, will be coming eventually to PC. Though, apparently the last few pieces of footage that we've seen of the game were of it running on Xbox, so we'll see. I'm definitely very interested in the technical aspect here, as if they really got the game running at 60fps on console, then what sacrifices did they have to make to get there, what were they able to maintain on Series X with its extra grunt, and what did they really have to sacrifice on Series S?
