DXR and Nvidia sounds way too locked-in. There should be more collaborative effort to do that through Vulkan and on all GPUs.

DXR works with AMD cards as well - https://www.dsogaming.com/news/amd-states-that-all-of-its-dx...

It's still MS only, so a bad option.

Gaming on non-MS PC platforms is a pretty small niche anyway though. I can see the appeal, but my guess is that the work to newly available marketbase ratio here isn't all that great.

So, good effort would be to help it grow, instead of perpetuating MS lock-in.

Playstation is nieche?

AMD actually uas released a real-time ray tracing library that’s included in Unity, and is Vulkan compatible, called Radeon Rays. [0]

And Crytek released a demo last week showing real-time ray traced reflections rendered on a Vega 56. [1]

Yep, that's more like it.

If your concern is lock-in, then DXR is currently your best option: DXR works for both AMD (with Microsoft's fallback path) and Nvidia, while the only existing Vulkan extension is Nvidia proprietary.

What kind of collaboration do you expect? AMD hasn't been paying a lot of attention to its GPU business the past years.

DXR is far from a good option, since it's a proprietary MS only API.

> What kind of collaboration do you expect?

Common Vulkan implementation focused on ray tracing that isn't tied to GPU (and OS naturally, since it's Vulkan).

How is DXR any more locked in than DX-anything else?

It is pretty much same lock-in as DX anything, so same bad at the later.
