Released 2025-11-24
|
|

|
|
|
|
|
|
|
- Improved occlusion query support:
|
|
|
|
|
- Add support for occlusion queries across multiple renderpasses.
|
|
|
|
|
- Improve performance by accumulating occlusion quieries in parallel,
|
|
|
|
|
and using untracked buffers to avoid encoder serialization.
|
|
|
|
|
- New descriptor state tracker implementation to improve performance.
|
|
|
|
|
- New descriptor set/pool implementation:
|
|
|
|
|
- The new implementation is less forgiving of applications that don't properly manage the lifetime
|
|
|
|
|
of their descriptors (and bind them after the objects they point to have been destroyed).
|
|
|
|
|
Use `MVK_CONFIG_LIVE_CHECK_ALL_RESOURCES=1` to revert any crashes this might cause,
|
|
|
|
|
or mark potentially-destroyed descriptors with `VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT`.
|
|
|
|
|
- Added working demo target for VisionOS in Cube Demo.
|
|
|
|
|
- Raise minimum target to _macOS 11.0 / iOS 14.0 / tvOS 14.0_
|
|
|
|
|
- Add support for `VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT`.
|
|
|
|
|
- Add support for the following extensions:
|
|
|
|
|
- `VK_KHR_maintenance9`
|
|
|
|
|
- `VK_KHR_shader_fma`
