DLSS isn’t exclusive to NVIDIA, at least in theory: AMD is reportedly testing an alternative implementation made by possible by Microsoft’s DirectML API, a component of DirectX 12 allowing for “trained neural networks” on any DX12 card. “The Deep Learning optimization, or algorithm, if you will, becomes a shader that can run over the traditional shader engine, without a need for tensor cores.” Will game developers actually implement, experiment and integrate support for DX ML into games? It also has to be said, it works reversed, DirectML could also make use of Nvidia's Tensor cores, certainly giving them an advantage. As the Radeon card would see a performance hit, whereas the RTX cards can simply offload the algorithm towards its Tensor cores. Time will tell, but this certainly is an interesting development as long as your graphics card is powerful enough, of course.
