How Well Are R8G8_UNorm and R8G8B8_UNorm Supported on Mobile Devices?
How well are and supported on mobile devices, and what should be considered when using them?
is relatively well supported on current mainstream mobile devices. It can be used for static texture reads as well as a render output format . can therefore be considered a relatively reliable choice for mobile platforms, including both static texture reads and render output. However, when it is used as a render target RT , targeted compatibility testing for Blend/Clear behavior is still required on some older or lower end devices, such as early OpenGLES 3.0 devices. This helps avoid rare cases where Framebuffer creation or rendering behaves unexpectedly. In comparison, is not recommended for direct use as a render target or rendering format . In actual use, it may cause compatibility issues such as color shifts or unexpected blending results , making its stability more difficult to guarantee. https://uwa overseas public.oss us east 1.aliyuncs.com/uploads/markdown/de0f66fc 281e 4150 89cd 6edd6c55e1eb.png If a project does need to use , testing should go beyond simply verifying whether the format can be created and displayed. On target devices, pay particular attention to: Whether the final color output is correct. Whether the blending results match expectations. Whether the rendering output is consistent across different devices . From a format selection perspective, can be considered a relatively reliable choice for mobile platforms. requires more caution, especially when it is intended to be used as a conventional rendering output format.
