Ray tracing in Final Fantasy XIV

[Valkyrie_Lenneth]

What even IS Raytracing? I hear that everywhere, but it's just a buzzword to me.

Raytracing, is a lighting technique. It bounces light off of every object for shadows, lighting, reflections, etc.

Movies have been doing it for years, but it has only been recent that hardware is able to render in real time.

It used to take them hours or days to render a single frame.
