I used quite a bit of path tracing in Unreal and it has come a long way ... still we might be many years away for full pathtracing. Toughest problem is refraction, glass etc. There are a lot of cheats that we have to use to get glass, and translucency right. I think we might need 3 more generations of GPU hardware for detailed path tracing, and unfortunately we need the next gen consoles to have enough cores for it. At the same time the software side on engine level can give huge boosts. The main advantage of path tracing is that you could have dynamic building games where a player adds to the environment while things look as good as a prebaked illumination. You can have moving objects that illuminate the scene accurately. Destructible dynamic objects that cast shadows and lights correctly when they disappear. For game devs, nanites and path tracing is freedom, they can imagine more, they have less limitations, less focus on visuals cheats, more focus on creating things. Path tracing is the biggest thing that happened in games for quite a while. By they way I don't like Nvidia, AMD or Intel ... they are all corporate blood suckers.
