@S.T.A.R.A.C. Your arrogance is not a virtue as well. Relax, life is too short already. I have never denied there are other methods which can solve the limitations of SSR, I was commenting on your video and what it was showing. In any case, is it better using one technology which solves all the equations at once - and I am NOT referring only to nvidia tech but also to Ray Tracing in general - or using three difference technologies which bring to the same result but are most likely more time consuming? Why nobody used these planar reflections until now when it was so convenient (I am talking about the last 10-15 years)? Are we sure performance are going to be good with millions of triangles on screen which need to be duplicated? RTX is still of course an hybrid version and yes, it is partially a cheat, but for now is what's getting closer to physical reality. I also agree with you that the tech is not ripe yet but it is the first stone for the future tech. PS: there is one example where planar reflections have been lately used and that is Resident Evil II Remake, namely in the interrogation room where there is a false mirror reflecting stuff properly, in that case the framerate sunk drastically. Using that kind of reflections on deferred engines bring to a huge computational expense, I read a paper about it many years ago.
