Microsoft is creating a new "advanced shader delivery" feature for the ASUS ROG Xbox Ally handhelds that might make loading games faster and more stutter-free. The company teased the upcoming feature alongside the announcement of the launch date for the first Xbox-branded handhelds and the company's new compatibility system for figuring out if games will run well on handhelds. It sounds like this new shader delivery system will require some amount of buy-in from developers, which means it likely won't impact every game at launch.
