With the XeSS SDK 2.0.1 availability there is now XeSS Frame Generation (Xess-FG) support, Xe Low Latency (XeLL), and XeSS Super Resolution (XeSS-SR) enhancements. XeSS Super Resolution now has Vulkan 1.1 support, DirectX 11 support on Arc Graphics, and other enhancements.
XeSS Frame Generation is Intel's solution for fluid motion and higher performance for Arc GPUs with XMX to provide a smoother gaming experience. Xe Low Latency is for minimizing input lag and more responsiveness while gaming with both discrete and integrated Arc Graphics.
Intel originally talked up these XeSS2 features back for their B-Series "Battlemage" launch.
The Intel XeSS SDK 2.0.1 is available from GitHub .
Sadly though the XeSS SDK assets are binary and the actual XeSS code is not open-source. The XeSS GitHub repository continues to host Windows binaries and just a few code samples but the actual implementation is not open-source. This is contrary to Intel originally talking up XeSS as "open-source" or even the Intel Knowledgebase continuing to claim it's open-source:
Description
Will the Intel Xe Super Sampling (XeSS) be open source and used for developers?
Resolution
Intel® Xe Super Sampling (XeSS) is open source. It is implemented using open standards to ensure wide availability on many games and across a broad set of shipping hardware, from both Intel® and other GPU vendors
Hopefully one day XeSS is actually fully open-source software and more useful for Linux gamers.
