I really like this idea for the Tobii Eye Tracker. Rendering games in high-res where you look could really amp up the FPS. The customizable sharpness bubble sounds cool too.
But yeah, to make this work, it’s probably going to need some teamwork with game devs and GPU folks like NVIDIA. They’d have to tweak the game engines and maybe the GPU software to handle the changing resolutions based on where you’re looking. Could even possibly be used in conjunction with DLSS-like features. If they can pull it off, it’d be a game-changer.
