Known issues and limitations

  • When using GPU encoding, all source image width and height must be divisible by 4.
  • GPU HW based encoding feature is only available on the Windows platform. Encoding is set only for BCn codecs and quality is limited when compared to CPU encoding.
  • BC6H is not supported with GPU HW based encoding.
  • KTX2 file formats for ATIn and DXT5 swizzled formats are not supported.
  • ATI1n, ATI2n processed images save as BC4 and BC5 formats.
  • Transcoding to ARGB_16F, ARGB_32F, and ARGB_8888 image formats is supported, all other channel formats have various data issues and have been removed until a fix is available.
  • Viewing glTF and OBJ models using Vulkan(TM) rendering shows blank views.
  • PSNR and Image diff analysis for mismatched channel source and destination types (F16, F32, HalfFloat, and 8bit) needs improvement.
  • BC6H for OpenCL is not available in this release.
  • If user-requested MIP Map level generation for GPU texture sizes in the GUI and CLI applications are invalid, they will automatically be -adjusted to the lowest settable limits.
  • Limited CubeMap support.
