> Valve’s immense resources would be better spent on making Source Engine work for more game genres; itself support Vulkan better Source Engine Vulkan support uses DXVK, and the main driver for DXVK development is Proton. So in a roundabout way, they are supporting Vulkan better. > or even default to Vulkan on Windows Is said Vulkan on Windows default better? Most pretty naive direct DirectX-to-Vulkan conversions (running DXVK under Windows) have sightly worse performance that just using DirectX directly, and the proprietary Radeon Windows and Nvidia Windows drivers hide a lot of implementation-specific optimizations and workarounds for common game and application bugs.
