Intel has explained in details and examples how image scaling technology XeSS works

Intel has published a fresh video in which its representatives described in detail how Xe Super Sampling (XeSS) technology works.
The Intel XeSS technique is designed to increase gaming performance by scaling the original image from a lower resolution setting below the native screen resolution to a higher resolution setting below the native screen resolution with maximum image quality.
In the new video, Intel representatives pretty much covered everything that was already known before.
Raster graphics and lighting in the game are rendered at low resolution, the game frame data along with motion vectors are passed to the XeSS scaling algorithm, and then passed through post-processing rendering tools, after which the user interface is applied to the picture in native resolution.
The XeSS upscaler uses not only motion vectors and important input frame data, but also temporal data from already processed (zoomed) frames, so the pre-trained AI algorithm within XeSS can more efficiently reconstruct image details.
The company shared fresh performance data from its flagship Arc A770 desktop graphics card and demonstrated how the use of XeSS technology affects performance in games such as Ghostwire Tokyo, Hitman 3, Arcadegeddon, SoTR, Diofield Chronicle, Super People, Redout 2 and Chivalry 2, which used different XeSS scaling presets: Ultra Quality, Quality, Balanced and Performance.
Intel also said that the company has started to work closely with UL Benchmarks, a developer of a comprehensive synthetic 3DMark test.
It is assumed that under this cooperation, a new performance test XeSS will be developed for 3DMark, as before there were separate tests to test the effectiveness of NVIDIA DLSS and AMD FSR on certain models of graphics cards.
According to Intel, their XeSS technology can be integrated into game engines as easily and quickly as AMD FSR.
In this case, the most effective results from XeSS will be observed in video cards equipped with matrix engines XMX.
For the gas pedals that do not have them, the company has made provisions for XeSS to work via DP4a programming instructions.
Thanks to this, XeSS will be supported not only by Intel Arc graphics cards and Intel Iris integrated graphics, but also by older Intel processor integrated graphics architectures (such as Xe-LP) as well as competing graphics solutions.
During video presentation games, which in perspective will support Intel XeSS scaling technology, were also listed.The first AAA-class game, which will support XeSS, will be Call of Duty: Modern Warfare II, which will be released on October 28.
