Intel XeSS Upscaler Set to Get Frame Generation After DLSS 3 and FSR 3: ExtraSS

Intel’s XeSS upscaling technology is all set to get frame generation technology, as indicated in the chipmaker’s SIGGRAPH Asia presentation. Officially known as ExtraSS, Team Blue’s Frame Generation technology works similarly to DLSS 3/FSR 3, combining spatial supersampling with frame interpolation, boosting rendering performance. This method removes CPU and GPU-related bottlenecks, relieving integrated solutions without extra hardware.

Intel officially calls its Frame Generation framework ExtraSSNet. It works like XeSS 1.1, using spatial-temporal information to predict inter-frame details, generating temporally stable results without losing object detail or shading accuracy.

We introduce ExtraSS, a novel framework that combines spatial supersampling and frame extrapolation to enhance real-time rendering performance. By integrating these techniques, our approach achieves a balance between performance and quality, generating temporally stable and high-quality, high-resolution results.

Leveraging lightweight modules on warping and the ExtraSSNet for refinement, we exploit spatial-temporal information, improve rendering sharpness, handle moving shadings accurately, and generate temporally stable results. Computational costs are significantly reduced compared to traditional rendering methods, enabling higher frame rates and alias-free high-resolution results.

Evaluation using Unreal Engine demonstrates the benefits of our framework over conventional individual spatial or temporal supersampling methods, delivering improved rendering speed and visual quality. With its ability to generate temporally stable high-quality results, our framework creates new possibilities for real-time rendering applications, advancing the boundaries of performance and photo-realistic rendering in various domains.

Intel’s ExtraSS has been internally tested using the Unreal Engine, showing notable improvements over conventional spatial or temporal upscaling filters, boosting performance and visual quality. At the time of reporting, there’s no telling when this Frame Generation technology will debut. Being an OpenSouce solution, it should work across Arc, Radeon, and GeForce cards, including integrated graphics solutions.
