While this may be technically true, it requires game designers to make a targeted effort to run on Metal. However, Apple has yet to add support for VAs or BDAs, insisting that existing argument buffer support is sufficient for what games want to do. According to Vulkan, their buffer device address (BDA) extension allows for the creation of complex data structures required for ray tracing, and useful for DirectX 12 porting. This limitation means CrossOver Mac can't support Tier 2 binding and therefore a lot of DirectX 12 games will not run.Īnother problem is that DirectX 12 uses GPU virtual addresses (VAs) to refer to resources for several things most significantly ray tracing. Metal’s limit of half a million is sufficient for Vulkan descriptor indexing, but not for D3D12. Metal only supports about 500,000 resources per argument buffer, so Tier 2 resource binding isn’t possible. Access to that many SRVs requires resource binding at the Tier 2 level. Generally, games need access to at least one million shader resource views (SRVs). Specific to DirectX 12 and Metal, there is an issue with limits on resources. In general, Metal does tessellation differently, and is missing geometry shaders and transform feedback.
