It looks like Microsoft wants to create its own analogue of Nvidia DLSS and AMD FSR technologies. This follows from the vacancies posted by the software giant.
Microsoft is looking for machine learning and rendering professionals through these jobs. Apparently, the technology will rely on the DirectX / DirectML API and will be available on both PC and Xbox consoles. It is important to note the reference to machine learning, that is, Microsoft’s technology will be some kind of intermediate option between DLSS and FSR, but at the same time it should not require hardware blocks to accelerate machine learning.
Of course, this technology should not be expected in the near future.
