--- Comment #6 from Samuel Pitoiset <samuel.pitoiset at gmail.com> ---
We won't add support for VK_FORMAT_D24_UNORM_S8_UINT for the following reasons:

- TC-compatible HTILE isn't supported (requires decompression passes)
- it consumes as much as VRAM as the 32bit format
- RadeonSI internally uses the 32bit format
- AMDVLK doesn't support it
- it's not required by the spec.

AFAIK, this is a win on NVIDIA but not on AMD hardware.

Please, use VK_FORMAT_D32_UNORM_S8_UINT instead.

Thanks!
