Description
VK_IMG_format_pvrtc
provides additional texture compression functionality
specific to Imagination Technologies PowerVR Texture compression format
(called PVRTC).
Note
As also noted in the Khronos Data Format Specification, PVRTC1 images must have dimensions that are a power of two. |
Deprecation
Both PVRTC1 and PVRTC2 are slower than standard image formats on PowerVR GPUs, and support will be removed from future hardware.
