转向优化为Windows掌机，微软被V社逼到了墙角

Core Viewpoint - Valve has opened SteamOS to third-party handheld devices, prompting Microsoft to shift its focus from developing a native Xbox handheld to optimizing Windows 11 for third-party devices [1][3]. Group 1: Valve's Strategy - Valve's SteamOS 3.7.8 version has been released, allowing third-party handheld devices to utilize the operating system [1]. - The rapid deployment of SteamOS has disrupted Microsoft's plans in the handheld gaming market [3]. - Steam Deck has revitalized the handheld gaming market, and the tailored features of SteamOS have given Valve a competitive edge [3][5]. Group 2: Microsoft's Response - Microsoft is prioritizing the optimization of Windows 11 for third-party handhelds instead of developing a native Xbox handheld [3][5]. - Phil Spencer, head of Microsoft's gaming division, indicated that most of Microsoft's games can run on devices like the ROG handheld, but they do not see a suitable entry point into the market [5]. - Windows 11 has become the dominant operating system for x86 handhelds, but its performance and battery life are inferior to SteamOS [10][11]. Group 3: Performance Comparison - Testing shows that SteamOS outperforms Windows 11 by at least 15% in terms of performance for games like Cyberpunk 2077 and The Witcher 3 [10][12]. - Battery life improvements on devices running SteamOS can range from 25% to 200% compared to those running Windows 11 [10]. - Windows 11 on handhelds has been reported to have more bugs and issues compared to SteamOS, affecting user experience [12]. Group 4: Market Implications - The competition between a closed SteamOS and an open Windows 11 is shaping the handheld gaming landscape [5][14]. - Microsoft's strategy mirrors Google's approach with Android, aiming to support OEMs while not directly entering the handheld market [14][15]. - If third-party manufacturers pre-install SteamOS on their devices, Windows 11's competitive advantage may diminish significantly [17].
