Only %40 slower on RTX 40 most likely. Remember this game will most likely abuse the heck out of shader execution reordering, opacity micromaps and all that jazz. Cost should be heavier on Ampere most likely.Only 40 % slower? Then it's definitely worth it.
Comparison hybdrid-ray tracing vs. path tracing:
Notable jump in quality. As long as the artists shape the world well path tracing solves lighting in games. The next objective should be to eliminate all pop ups, display even more geometry etc.
