Microsoft is the one company I expect to push RT the hardest. Especially since they intend to keep supporting the XBO for a couple of years. And what better way to differentiate games than to have the XSX use RT
Ultimately I think that we will see games benefitting from ray traced ground truth content , but not via directly being rendered, but being painted in by AI.
A little like DLSS works, but focussing not purely on hallucinating the extra resolution.
