Intel shares XeSS 3.0 SDK for game devs with 3x and 4x MFG modes — but it still hasn't followed through on its open-source promise

Intel has released the XeSS 3.0 SDK, featuring 3x and 4x multi-frame gen (XeMFG) modes for game developers, similar to Nvidia's DLSS MFG. Despite promises of open-sourcing XeSS, the SDK remains closed-source. Upgrading from XeSS 2.0 to 3.0 is straightforward for developers, but the lack of source code may hinder modding efforts. XeSS 3.0 focuses on multi-frame gen, limited to DirectX 12 Windows titles, with no support for Linux or Vulkan API. While a significant update for Intel, XeSS 3.0 aims to boost performance but faces challenges in adoption by game developers.
