If you qualify RTX as "realtime raytracing" then it has been possible for a long time now. Of course this uses way more smoke and mirrors :) https://www.youtub

  No I mean it in the sense of using ray tracing for the full Global Illumination of a full game scene. Obvs there are lots of titles some a few years old where RTX is used for specific effects like specular reflection or ambient occlusion but where the lighting is still traditional. Ray marching a SDF based scene is also pretty easy but that’s more like a world inside a shader than anything resembling a full game scene.

    Metro Exodus Enhanced Edition uses RT for basically all lighting, doesn't it? https://www.youtube.com/watch?v=NbpZCSf4_Yk https://www.youtube.com/watch?v=NbpZCSf4_Yk Same with Minecraft RTX https://www.minecraft.net/en-us/updates/ray-tracing https://www.minecraft.net/en-us/updates/ray-tracing Though both still calculate the lighting over several frames, so if you want to be pedantic you could argue that it's not strictly real time.
