You can tell because it reflects things off screen and are also perspective correct, unlike cube maps which have issues with alignment and having the strange effect of seeming like its infinitely far away. You can even see real time reflections on pools of blood, theyre not screen space or cube maps. The puddles absolutely do have lumen ray tracing. Where does RT and it's impact to performance come into play in a title like this? My point about hardware accelerated RT is because his hardware would dictate these issues, except the puddles have no ray tracing, at all. I know that Lumen runs on a 6 year old 1080 too, so my point is the convo is odd to me. I'm sorry but this isn't some extensive RT game. Just like Nvidia's RTX it can do any combination or individual effect of Reflections, lighting, global illumination, or shadows. Lumen is vendor neutral, that's what UE developed it.

Also, it does use accelerators if it detects you have them regardless of if they are AMD or NVidia, software mode is just a fallback.

Please share specs, so we can help or spark a greater discussion :) Did you not read the presentation on what lumen is? Also, it does use accelerators if it detects you have them regardless of if they are AMD or NVidia, software mode is just a fallback. I have quite a few Nvidia cards and a couple AMD, so I can always double check if it's older cards without any RTX feature set or RDNA 2 even matters.

Originally posted by Ivylifestyle:What is your PC specs? Software lumen runs on hardware with zero RT capabilities / isn't proper HW accelerated RT ( I don't consider it RT, just fancy lighting software to mimic it).
