More on topic though, I think that cherno video wasnt too informative about details, but it is still nice to have actual programmer focused slightly on graphics go over the demo in layman terms.

I wonder if majority of triangles are rasterized with compute shaders, is the regular fixed function rasterization even used at big capacity, or are they more idle than usual.
