Intel Develops ExtraSS, a Frame Generation Technology Using Extrapolation

The new technology aims to reduce latency issues present in rivals Nvidia's DLSS 3 and AMD's FSR 3.

Intel is developing a new frame generation technology called ExtraSS, which is designed to rival Nvidia's DLSS 3 and AMD's FSR 3.
Unlike DLSS 3 and FSR 3, which use frame interpolation, ExtraSS uses frame extrapolation, a technique that predicts the next frame using data only from previous frames.
ExtraSS's frame extrapolation approach reduces the latency issue present in DLSS 3 and FSR 3, but it also faces challenges such as disocclusion artifacts.
Intel's researchers claim they have found a solution to the disocclusion issue and that ExtraSS provides high-quality results by utilizing the geometry buffer for warping.
ExtraSS is still in the research phase and is expected to be applied to Intel's XeSS utility in the future.
