This video is probably missing the point already, since you're already comparing ray tracing to slightly more integrated ray tracing.
But something about this "path" tracing still doesn't look right to me.
For example, at 6:44, this scaffolding on the ceiling is not shaded correctly. Parts of it should be way darker than they are.
I love it. You guys keep nitpicking.
I suspect issues like the one I pointed out above are more due to not sending out enough rays, or taking shortcuts with geometry interacting with light. When we talk about path tracing, that implies no shortcuts are being taken.
Even if the lights are extremely bright, you'd still expect the dark parts to be dark.
If the issue is actually due to the number of rays, I guess using native resolutions may fix it, and that may be fine.
Ray tracing can suck it, doesn't even come close to making my weewee feel funny. Give me a true and proper VR mode instead.
