Intel engineers are working to integrate XMX-accelerated Intel XeSS into Valve’s Proton (Steam Play), according to reports that point to new code submissions aimed at adding XeSS support in the Proton toolchain.
The changes discussed include updates to related components used to run Windows games on Linux, including VKD3D-Proton and DXVK, which translate DirectX workloads for use on Linux and the SteamOS ecosystem. The effort is described as leveraging Intel’s XMX acceleration capabilities and bringing XeSS features into the Proton pipeline.
Outlets characterize the work as both a technical integration task and a potential step toward broader hardware support for future Intel-powered handheld gaming PCs running SteamOS. While details on timing and which devices will be supported are not specified in the available summaries, the focus across sources remains on enabling XeSS through Proton rather than on any standalone Intel application.
