Screen space tricks #75

I wonder if screen space lights and reflections could be used to reduce the RT load? As in... using the RT to fill in the gaps for only things that are bounced from offscreen. Also... in Doom, the player is only able to look up and down, so I wonder if screen space could also be used by itself to drastically improve performance on lower cards, as a less expensive option?

I think a lot of the charm in those RT game mod projects is that the game is 100% raytraced, with no hacks and shortcuts whatsoever. Hybrid raytracing is a good solution for modern AAA games, but I think old games shine the most when they're 100% raytraced.
