DLSS and RTX are the same way, but instead of communicating between two hardware products, it's communicating between two software components, and then translating those messages onto commands for specialized hardware.
Both DLSS and RTX are a simpler, more specific casez of GPGPU, so they likely could've opened and extended CUDA, extended OpenCL, or extended Vulkan/DirectX instead, with the hardware reporting whether it can handle DLSS or RTX extensions efficiently. CPUs do exactly that for things like SIMD instructions, and compilers change the code depending on the features that CPU exposes.
But instead in all of those cases, they went with proprietary and minimal documentation. That means it was intentional that they don't want competitors to compete directly using those technologies, and instead expect them to make their own competing APIs.
Here's how the standards track should work:
That's it. Step 1 shouldn't take much effort, and if they did a good job designing the standard, step 5 should be pretty small.
But instead, NVIDIA ignores the whole process and just does their own thing until either they get their way or they're essentially forced to adopt the standard. They basically lost the GSync fight (after years of winning), and they seem to have lost the Wayland EGLStream proposal and have adopted the GBM standard. But they win more than they lose, so they keep doing it.
That's why we need competition, not because NVIDIA isn't innovating, but because NVIDIA is innovating in a way to lock out competition. If AMD and Intel can eat away at NVIDIA's dominant market share, NVIDIA will be forced to pay nice more often.
Every single thing about what you're discussing literally guarantees that GPUs are dogshit. There's no path to any of the features we're discussing getting accepted to open standards if AMD has input. They only added them after Nvidia proved how much better they are than brute force by putting them in people's hands.
Standards do not and fundamentally cannot work when actual innovation is called for. Nvidia competing is exactly 100% of the reason we have the technology we have. We'd be a decade behind, bare minimum, if AMD had any input at all in a standards body that controlled what Nvidia can make.
We're not going to agree, though, so I'll stop here.
The process I detailed does not require consensus before a product can be released, it just allows for that consensus to happen eventually. So by definition, it won't impede progress. It does encourage direct competition, and that's something NVIDIA would rather avoid.
