In the wake of the Qualcomm Snapdragon X and the ever-present desire to push Windows 11 on Arm to the forefront, Microsoft announced and explained an exclusive feature for Arm Windows 11 today— Auto SR. Microsoft Auto SR, or "Automatic super resolution", is an AI-powered image upscaling solution intended to be used similarly to DLSS, FSR, and other such upscaling solutions. It should not be confused with the more recently announced DirectSR, which functions as an API to integrate any upscaling solution from any vendor easily.
Based on the information on the official Microsoft support page for enabling this feature, there are some significant downsides. However, this is still quite nice to have since Qualcomm's Snapdragon X may otherwise be restricted in upscaling options, particularly in titles without existing upscaling settings. It also shows that Microsoft is still serious about Windows 11 on Arm, and the Snapdragon X CPUs look pretty powerful indeed, even while running x86/x64 applications.
