Intel Releases XeSS 3 SDK on GitHub as a Closed-Source Tool

Despite earlier commitments, Intel’s new “open-source”upscaling technology continues to be distributed as closed-source software with the launch of the XeSS 3 SDK.

Intel Introduces XeSS 3 SDK on GitHub for Game Developers, Remains Closed-Source

Intel has unveiled the XeSS 3 SDK (Software Development Kit) on GitHub, designed to enhance accessibility for developers interested in its advanced AI-driven upscaling and frame-generation capabilities. Although this release signifies progress in making the latest upscaling technologies available, the SDK remains closed-source as it is exclusively distributed in proprietary Windows binaries.

The introduction of XeSS 3, along with Multi-Frame Generation, marks a significant development, which initially launched alongside Intel’s Panther Lake processor series. This technology has since become compatible with various hardware, including all Arc Alchemist and Battlemage products. Nevertheless, the SDK’s exclusivity to the Windows operating system is disappointing, especially considering Intel’s prior promises regarding open-source intentions. Regrettably, the XeSS 3 SDK’s foundation on binary-only Windows libraries has left many developers and advocates of open-source solutions disillusioned.

In comparison, AMD’s FidelityFX Super Resolution (FSR) has adopted a more transparent approach by allowing developers access to the source code for examination and modification. This contrasts sharply with Intel’s decision to keep XeSS proprietary, which could potentially hinder widespread adoption of the technology. Many gamers are currently pushing their hardware to the limits in pursuit of higher frame rates. For those who cannot afford expensive upgrades, Intel’s Multi-Frame Generation may present a viable solution, particularly for users of Intel hardware.

However, it’s unfortunate that Linux users will be left without access to XeSS 3.0 and Multi-Frame Generation. It is hoped that in the future, Intel may reconsider its position and shift towards an open-source model, which would accelerate adoption and expand support for newer upscaling technologies across a broader spectrum of games.
