It is rumored that Microsoft has abandoned the current Esram API and intends to introduce a new DIRECTX12 based API.
In an interview, Microsoft Senior manager Brad said the Xbox's Esram has always had great potential, but the potential is probably just because it can be optimized for exploration. But optimization alone does not seem to satisfy the player's demand for the Xbox.
For this reason, Microsoft intends to replace the DIRECTX11 API with DirectX12 APIs. Brad says it will be a huge difference, and the Xbox will be a separate optimization tool to ensure that the game achieves optimal optimization with some algorithms.
We all know that the 1080p has been the pain point of Xbox One. The birth of the DirectX12 may turn out to be a performance twist for the Xbox One. DirectX12 gives people too much anticipation, which naturally includes cross-platform development.
