Intel is preparing to add XMX-accelerated XeSS support to Valve's Proton compatibility layer, replacing the slower software-based upscaling currently used. The XMX cores on Intel graphics cards will significantly accelerate upscaling and deliver substantial performance improvements for Linux gamers.
Intel is promoting XeSS 3.0, which features multi-frame generation (MFG) capable of inserting up to three generated frames between two rendered frames, resulting in up to a fourfold increase in frame rate using MFG. This technology is similar to NVIDIA's DLSS MFG and reflects the growing trend of AI-generated frame insertion.
The latest "Panther Lake" SoC with Xe3 cores includes eight vector engines, eight matrix engines (XMX), and a dedicated ray tracing unit per core. These execution units now operate with higher utilization thanks to refined thread dispatch and load balancing. The vector and matrix engines double peak FP16 and INT8 throughput compared to Xe2, benefiting both traditional rendering and AI-assisted tasks such as denoising, upscaling, and frame generation.
Supporting XMX-accelerated XeSS will finally give Intel Xe gamers on Linux a much-needed performance bump.
