That's the kind that would most benefit Halo Infinite's graphical style. I don't know if it's more or less demanding, I forget the specifics on comparative demand to something like ray traced reflections, but I do feel it's the one that will most make Halo Infinite look more incredible with the visual style it's aiming for.
I definitely want Ray Tracing in Halo Infinite, just not at the potential early launch compromise of the core game without ray tracing. If they had enough time to do both things that would be great, but it's clear 343 is telling us that there were other things that were a higher priority for them. Many, I think, tend to forget that there has never been any Halo game even remotely close to what this game is trying to accomplish, not even the most impressive parts of Halo 3 compare to what they're aiming to do with the size, openness and level of freedom being offered in this game. Save for the more expectedly linear interior sections of the game, the outdoors sections of Halo Infinite's campaign could possibly be as or more open than both major scarab encounters in Halo 3, with many more tactical possibilities.
