GART: Games and Applications using RayTracing

Yes, the rationale makes sense. You can obviously makes games run faster with rasterization but only under particular limitations that we’ve come to accept as normal.

 

Pretty sure the only unique advantage with RTXDI/ReSTIR is that you can use it to apply shadow rays for every light sources in the scene and temporal reuse of shadow rays is a major component of the technique. You could already render thousands of dynamic light sources if you did clustered forward shading and support arbitrary primitive shapes for light sources too with linearly transformed cosines ...
