Im not sure why AMD didn’t bother with this, but they have in recent history had hardware/driver bugs that caused them to scrap entire features on thier GPUs.
What are some features they scrapped due to driver bugs?
AMD bugs with dynamic parallelism despite to the point it disabled the feature later, but also is required for raytracing extension to work in the first place.
AMDs variable rate shading was supposed to be on VEGA, didn’t happen, then was supposed to be on 5000 series, also didn’t happen (might be wrong about the 5000 series, but that’s what I remember, and afaik, and tried to pass off dynamic resolution as a type of VRS as a consolation, which it isn’t)
AMD only supporting harware ROV in their windows DX12 drivers, despite it being implemented by the mesa team for vulkan.
