> without a super expensive RTX-like raytracing card. Without a card that supports hardware raytracing, Lumen falls back to a software raytracing mode that carries some limitations[1] The min-rec non-RTX GPU is a GTX 1070, so there's (roughly) only one generation of supported GPUs that are supported but don't support hardware raytracing. My prediction is that the software fallback will eventually lose support and become deprecated as raytracing cards become more common.
