The Scaling Technology of Intel XesS was checked by Shadow of the Tomb Raider and compared to NVIDIA

Intel Arc A770 and NVIDIA GeForce RTX 3070 were used for testing.

XesS version 1.187 technology expert Digital Foundation Alex Battalya considers the second generation of scaling techniques to be the same as NVIDIA DLSS 2.0 and AMD FSR 2.0. All three use time scale algorithms, where data are taken not only from the current frame but also from several previous ones, which form the final image of a higher resolution.

XeSS is a machine learning algorithm that uses the XMX graphics cores of Arc Alchemist. Intel also develops the XesS software analogy, which is used for the DP4a algorithm and will be supported by external video maps without those XML cores. The XesS efficiency is worse in this case and the ecosystem is wider.

Digital Foundation experts note that the use of XesS to scale an image from the original resolution of 720p in 1440p increases frame time by 2 ms. However, the final result of the image conversion is worth it.

When you scale the image from resolution 1080p to 4K using XeSS "Production capacity", the frame time is increased from 8.8 to 12.2 ms. By comparison, the DLSS 2.3 technology on the GeForce RTX 3070 video card increases the frame time by 3.8 ms under the same conditions.

According to the surveyors, XesS will receive the "Macial Quality" mode, which FSR 2.0 and DLSS 2.0 do not have. This mode uses the original image in a higher resolution than the "Quality" mode, but increases the productivity of Shadow of the Tomb Raider when scaling up the picture to 4K and 1440p by 16 and 23% respectively. The use of XesS in Shadow of the Tomb Raider mode shows an increase in the performance of the game from 52 to 88% over the original resolution.

The XeSS performance with beaming was also tested in a synthetic 3-DMark test, where it increased the frequency to 177% of the original design, taking into account different quality modes.

In its current form, XesS is certainly more effective than the same FSR 1.0 and DLSS 1.0, and in many cases provides better quality than the original image. The most striking example is the image with the fishing net below. On the right frame, the image is the image in the home resolution with the intragame smoothing of TAA. The average image is XesS and on the left is DLSS 2.3.2.

On the other hand, in some cases, the use of XeSS in the test resulted in image artifacts. The character ' s shirt below can serve as an example.

An in-depth analysis of XesS technology is available in the 28-minute video produced by Digital Foundation.

Since XeSS is not yet available for regular gamers, there is a possibility that many of the shortcomings that Digital Foundation's team has highlighted in its review will be corrected for the release.
