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.
