Giovanni Mascellani (@giomasce) commented about libs/vkd3d/device.c:
VK_EXTENSION(KHR_SAMPLER_MIRROR_CLAMP_TO_EDGE, KHR_sampler_mirror_clamp_to_edge), VK_EXTENSION(KHR_TIMELINE_SEMAPHORE, KHR_timeline_semaphore), /* EXT extensions */
- VK_EXTENSION(EXT_4444_FORMATS, EXT_4444_formats),
Aren't we supposed to enable the extension features too when creating the device?
