We have just received word that Intel has poached the Lead Research Scientist of Facebook Reality Labs, Anton Kaplanyan. He will be joining as Vice President of Graphics Research of Intel AXG Group and will be a key player in furthering gaming technology (including machine learning-based supersampling which Intel currently calls XeSS). Anton has quite the pedigree and was formerly a research scientist at NVIDIA and has even done a stint at CryTek.

NVIDIA's DLSS is one of the killer apps present in Turing/Ampere GPUs and Anton was part of the team that pioneered those approaches. His LinkedIn states "worked on RTX ray-tracing hardware design and simulation, invented the direction of 1 sample/pixel real-time denoising, applied machine learning to real-time graphics for the first time". I am sure his work will turn out to be extremely valuable for Intel's GPU ambitions and considering he has done a 4-year stint at Facebook between this, there is no non-compete threat here either and no confidential information requirement.
