Microsoft's Windows 11 platform is facing competition from alternatives like SteamOS and Bazzite in the handheld gaming market, leading users to replace Windows 11 on third-party devices. To address this challenge, Microsoft is launching the Full Screen Experience (FSE), which aims to enhance the gaming environment on Windows 11 by streamlining the user interface. Initially exclusive to Asus ROG Xbox Ally and Ally X, FSE will be available to all Windows 11 handhelds starting tomorrow. The rollout was announced on Xbox Wire and will expand to more Windows 11 PC form factors through the Xbox and Windows Insider programs. Initial impressions suggest that while FSE improves game booting convenience, it has not yet significantly boosted game performance.
