It was broken, because it wasn't passing down the offsets at all. There is no support for this in Metal. While it would be easy to emulate by doing four...

It's useful even without geometry shaders using `VK_EXT_shader_viewport_index_layer`, which allows you to set the viewport index from a vertex or tessellation evaluation shader. Maybe we should see about getting the...

Er, uh, why did you close this? If there's a problem with our code, and you have a fix for it, you should probably submit it to this repo. We'd...

Theoretically, it should be possible to support the `VK_NV_ray_tracing` extension on Mac, using the Metal Performance Shaders framework which uses a very similar technique to accelerate ray tracing. At this...

@gpx1000 ^^

Part of the problem is that Metal doesn't let you place sparse tiles at specific locations inside of sparse heaps, whereas Vulkan and D3D12 do.

So this happens because DXVK sets a bunch of usage bits (or doesn't set usage bits at all when creating an image view). I thought I got a change to...
