Intel finally released the SDK (Software Development Kit) for its XeSS 2.0 stack of technologies to the public through its GitHub repository yesterday. The XeSS SDK 2.0.1 offers a more streamlined and user-friendly process for developers to integrate Intel's latest XeSS-SR, XeSS-FG, and XeLL technologies into their games. After a bit of research, we discovered that despite all these major updates, XeSS remains a closed-source and Windows-first technology.
Intel's latest endeavors into the budget segment with the Arc B580 and B570 in December came with a new suite of updates to its XeSS stack. XeSS 2 is now subdivided into three main branches: XeSS-SR (Super Resolution), XeSS-FG (Frame Generation), and XeLL (Low Latency). XeSS-SR and FG target the respective upscaling and frame-generation tech found in Nvidia's DLSS and AMD's FSR offerings. Meanwhile, XeLL serves as Intel's response to Reflex and Anti-Lag from Nvidia and AMD, respectively.
