IT Home reported on December 19 that Intel recently attended the Siggraph Asia 2023 event in Sydney and published an articleAn overview of a new frame generation technique called extrass.
Intel's XESS technology is hardware-agnostic, meaning it is compatible with NVIDIA and AMD GPUs.
Judging from the previous test data, Intel's XESS matches NVIDIA's DLSS and is ahead of 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 expanded to include frame generation technology, which can increase the frame rate of games while maintaining image quality through interpolation technology.
Nvidia in DLSS 35 Updated to include frame generation technology;And AMD is in FSR 3Version 03, the frame rhythm issue was resolved to provide higher fidelity.
According to the disclosed technical documents, Intel outlined a frame generation technology called ExtraSS, which is translated in part as follows:
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 leverages the lightweight Warp module and ExtraSSNet for refinement, leveraging spatiotemporal information to improve render clarity, accurately handle moving shadows, and produce time-stable results. The computationally expensive compared to traditional rendering methods is significantly lower, enabling higher frame rates and aliasing-free high-resolution results.
When evaluated in Unreal Engine, ExtraSS has advantages over traditional single-space or temporal supersampling methods, resulting in faster rendering and better visual quality.
With its ability to produce time-stable, high-quality results, our framework opens up new possibilities for real-time rendering applications, pushing the boundaries of performance and first-class photorealistic rendering in a variety of fields.
Intel's Extrass frame generation technology focuses on "frame extrapolation" rather than "frame interpolation", and the effect is almost identical, with the main difference being how frames are generated.
