  • MoltenVK

    MoltenVK is a Vulkan Portability implementation. It layers a subset of the high-performance, industry-standard Vulkan graphics and compute API over Apple's Metal graphics framework, enabling Vulkan applications to run on macOS, iOS and tvOS.

  • For the brave ones who are willing to get their hands a little dirty, I discovered some ways to both improve performance and get rid of the graphical issue with the ocean on Kerbin. To do so, you need to build the latest MoltenVK and grab the latest DXVK release and update the proper files in your Crossover installation. In addition, you need to copy the dxvk.conf file and place it in the same directory as KSP2_x64.exe. Set enableRefactoring, ignoreGraphicsBarriers, and enableAsync to True in this config file. My experience from these tweaks was a 20-25% increase in FPS.

  • DXVK-macOS

    Vulkan-based implementation of D3D10 and D3D11 for macOS / Wine
