Cpu based realtime raytracing has been around a long time, even in 2008 The video above is just to explain how a game with cpu based realtime raytracing would work(note that everything in the video above is rendered by the cpu thats why its a bit messy), to make it short the cpu calculates the position of a set of rays with a set of vectors and the gpu then knows what to reflect from outside of the camera view. This was used in an gta mod that ran flawless with ambient occlusion raytracing on 2013 hw!!!!(as seen from the reflection from objects outside of the camera view) Just a reminder this is the bf v benchmark before the downgrade! and thats what they promised there is no denying in the fact that this was a professional preplaned scam from the beginning preying on the hype a prerendered video and fake benchmark results would produce which nvidia has done in the past to hype scams! https://www.geek.com/games/futuremark-confirms-nvidia-is-cheating-in-benchmark-553361/ If you want raytracing make pressure on gamedevs to do sth for theyre money other than lootboxes, they have no excuse if a hobbyist in his basement could do it. Think twice before spending 1000$ on a scam.
