Intel is developing XeSS frame generation technology - ExtraSS

Intel's XeSS technology is hardware independent, meaning it can be compatible with Nvidia and AMD GPUs.

Based on previous testing data, Intel's XeSS matches NVIDIA's DLSS and leads AMD's FSR. XeSS is also an open-source technology, which means it can be easily integrated into games.

However, NVIDIA's DLSS and AMD's FSR have also added frame generation technology, which can improve game frame rates while ensuring image quality through interpolation techniques.

Nvidia has updated to include frame generation technology in DLSS 3.5; In the FSR 3.03 version, AMD solves the frame rhythm issue and provides higher fidelity.

According to the disclosed technical documents, Intel has outlined a frame generation technology called ExtraSS, and IT Home has translated the following content:

ExtraSS combines a novel framework of spatial supersampling and frame extrapolation to enhance real-time rendering performance.

By integrating these technologies, our approach balances performance and quality, producing time stable and high-quality, high-resolution results.

ExtraSS utilizes lightweight deformation modules and ExtraSSNet for refinement, utilizing spatiotemporal information to improve rendering clarity, accurately handle moving shadows, and generate time stable results. Compared with traditional rendering methods, the computational cost is significantly reduced, enabling higher frame rates and high-resolution results without aliasing.

When evaluating with Unreal Engine, ExtraSS has advantages over traditional single spatial or temporal supersampling methods, thereby improving rendering speed and visual quality.

With its ability to generate high-quality results with stable time, our framework has created new possibilities for real-time rendering applications, pushing the boundaries of performance and photo level realism rendering in various fields.

The focus of Intel ExtraSS frame generation technology is on "frame extrapolation" rather than "frame interpolation", and the two have almost the same effect, with the main difference being the way frames are generated.
