An ambitious developer has taken the lead in enabling Intel's XeSS super resolution and frame generation technologies for Linux users, specifically within SteamOS and Proton game environments. This experimental release, which leverages the dedicated XMX units of Intel GPUs, delivers substantial performance improvements, with one game seeing a 145% boost, showcasing the potential for enhanced gaming experiences on Linux-based systems equipped with Intel Arc graphics.
Developer Unlocks Intel XeSS on Linux, Boosting Game Performance
Intel had previously announced plans to integrate its XMX-powered upscaling and frame generation capabilities into Linux via Valve's Proton compatibility layer. However, an independent developer, identified by their GitHub handle HHHHanasak1, has released an experimental version that brings these features to fruition ahead of Intel's official timeline. This project, detailed on GitHub and highlighted by Phoronix, offers a significant upgrade for Linux gamers.
The new implementation provides 'true Intel XeSS super resolution and XeSS Frame Generation' for games running through Proton, utilizing the GPU's XMX (matrix) units instead of the less efficient DP4a fallback. Developed on a OneXPlayer 3 handheld, which incorporates the Intel G3 Extreme chip found in devices like the MSI Claw and Acer Predator Atlas 8, the solution has also been successfully tested on a discrete Arc B580 GPU.
Early benchmarks reveal impressive results. In Cyberpunk, the transition to XMX processing for upscaling alone yielded a 29% performance increase. When combined with XeSS Frame Generation, the performance surged by an astonishing 145%. While these figures are from a single title, and other games like Forza Horizon 6 showed a more modest 16% uplift from the XMX implementation, the overall frame rate benefits from 3x frame generation are still substantial.
Installation of this experimental driver is described as straightforward, involving unpacking an archive and executing an install command. Once installed, games automatically run with the patched drivers, eliminating the need for specific launch options. A key requirement is using the native Steam client, as the Flatpak Steam client is not currently supported.
This community-driven effort is a welcome development for the Linux gaming community, particularly for those with Intel Arc graphics cards. While the expectation remains for Intel to release an official, widely available version for SteamOS and other Linux distributions, this experimental solution serves as an excellent temporary measure. Given the current market landscape where graphics card prices can be prohibitive, Intel's Arc B580 and B570 cards offer relatively affordable options at around $330 and just over $300, respectively. This makes them attractive choices for building Linux gaming setups, now made even more compelling by the enhanced performance capabilities.
A Game-Changer for Linux Gaming and Intel's Ecosystem
This pioneering project not only highlights the ingenuity within the open-source community but also underscores the urgent demand for advanced graphics technologies on Linux platforms. For gamers, this means a tangible improvement in performance and visual fidelity without having to wait for official support. For Intel, it’s a clear signal to accelerate their Linux integration efforts, ensuring their hardware can reach its full potential across all operating systems. This development could pave the way for Linux to become an even more viable and appealing platform for PC gaming, encouraging broader adoption of Intel Arc GPUs in this space.
