    Hi,

    I seem to be running into a bug in which Alpha8 images are being used as 32-bit RGBA textures in Windows Store Apps. Unity Profiler shows the texture usage of the 1024x1024 image as 1.0MB, but using the DirectX debugger in VS2015 and Windows Performance Analyzer, it shows the texture being uploaded as true color.

    Texture Settings in Editor:

    Reported by Unity Profiler:

    Visual Studio DirectX diagnostic tool:

    Is this a known bug, or are Alpha 8 images unsupported on Windows apps? Unity version is 5.2.1f1

    It probably depends on DX11 feature level, also please submit a bug via bug reporter.
