> I'm surprised, I thought this was a dead area for research and AI super resolution had fully supplanted it. There is no open source solution of the AI variant. There are currently only DLSS (Nvidia) and XeSS (Intel), and both are proprietary. The one open source solution is AMD's FSR (MIT license), which doesn't use machine learning. So naturally Arm and Apple build on FSR for their products instead of developing an AI solution from scratch.
