MoltenVK 1.4.2-rc1 has been released as the first candidate for Apple's Vulkan portability layer, offering full Vulkan 1.4 support for macOS, iOS, and tvOS while raising the minimum system requirements to macOS 12.0 and iOS/tvOS 15.0. Key features include native sampler min/max filtering and gl_DrawID support, improving shader execution and drawing efficiency. The update also addresses a significant number of GPU-specific bugs, particularly for older Mac 1 GPUs, although some fixes related to Apple Silicon were reverted for further review. As this release is a candidate, additional updates and fixes are anticipated before the final version becomes available
