> there will be always the case that you need to wait for such primitives to be made available. About the features thing, when it comes to CPUs you don't really need to wait for features unless it's something like SIMD support but otherwise the programming model is general enough that I don't need to think about CPU features too much. What I'm wondering is, as GPUs become more general, will the situation become more like CPUs. For example, I saw an example where someone wrote a shader, using work graphs, to rasterize triangles. Once you can do things like that, it seems like the need for new primitives is far less.
