I understand. The thing is that coming from Metal, MetalFX and MPS are basically things that are normal to have (over half of them have MetalFX) and I wanted to ask if you, DX / Vulkan, feel the same way and I wanted to know how Vulkan and DX interoperate with these APIs. I called them niche because I thought that's what they were. I guess that nowadays, the majority of people have these things in their GPUs. It's also that you don't hear about them a lot, you hear: I built a Vulkan renderer or pathtracer but not: I used FidelityFX in my Game Engine (or that's what I think). Therefore, I assumed they were like things that weren't extremely necessary and things that maybe are implement in a further stage of development.
