The Mac efforts rely on MoltenVK for and Vulkan needs which itself relies on the underlying Metal API. As I understand it Asahi/Honeykrisp driver for Vulkan does not rely on the Metal API so it actually can do more conformant Vulkan than Crossover/Whisky can. For example tranform feedback and other geometry shader stuff will work on Asahi. MoltenVK is working on it, but not there yet.
- dagmx 2y agoYou’re ignoring D3DMetal which is what is most commonly going to be used and equivalent to what Proton is doing to convert D3D to VK. Most games are D3D. A very small minority are Vulkan from the get go.
- achandlerwhite 2y agoOn many games I have tried DX => DXVK => MoltenVk => Metal is significantly faster than DX => D3DMetal. For example XCOM2 is about twice the frames per second (yeah it has an official Mac version but it is even slower).
