Maybe they didn’t choose the best comparison shots, but the technical details of what’s happening with this mod is really interesting. With his mod, it’s approximating global illumination in world space vs the standard screen space methods, so it’s accounting for bounced lighting from areas offscreen.

The cool thing about it is it’s implemented via Reshade, so you don’t need a ray-tracing card to make it work as far as I can tell, and it should be compatible with games that RTX remix won’t be able to touch.
