  "account": "Intel's experimental project successfully enables Intel XeSS super resolution and frame generation on the XMX units within Proton games, eliminating the need for the DP4a fallback. A shim application, igdext64.dll, responds to XeSS driver queries, similar to Intel's Windows driver. The patched Mesa ANV compiles XeSS kernels using Intel's IGC on the user's machine. Frame generation now functions identically to the Windows version, including multi-frame generation, and boasts lower latency by default since the latest release. Games that support FSR 3.1 or higher can now utilize XeSS super resolution and frame generation instead of FSR. The patch series for Mesa 26.1.2 and 26.3.0-rc3, developed by Michael Larabel, has been tested on various hardware configurations, including Arc B390, Xe3; Arc B580 (Xe2); A310 (Xe-HPG); and an MSI Claw handheld.",
  "summary": "Last month I wrote about Intel working on adding proper XeSS support to Steam Play (Proton). While those efforts haven't yet been completed for benefiting Linux gamers running Intel Arc Graphics, in the meantime an independent open-source developer has managed to get XMX-accelerated XeSS working under Proton...",
