What changed in the official release
The new version of Auto SR works when the handheld is undocked, unlike the preview version, which did not support handheld play. It can now work directly on the handheld's screen, including when the device is running on battery power.
Auto SR can now work with games running at 1080p on default. During the preview, users had to lower the game's resolution before the technology could kick in. Microsoft warned that when using 1080p on handheld, "performance may not be as optimal as other configurations." The company said users should still see visual quality improvements, especially for older games.
The new Auto SR can reach framerates up to 120 fps, while the preview version could only hit between 60 to 75 fps. Microsoft explained that this would make fast-paced and competitive games like shooters feel and look smoother on screen.
Auto SR now supports HDR visuals. Both the higher framerate capability, which Microsoft calls "Performance Mode," and HDR support will be rolling out with future Windows updates.
