Idk as an "intermediate" graphics programmer, the explicitness and lack of abstraction in Vulkan is one of the killer features for me. "Wiggle room" in higher-level API's like OpenGL is one of the things that made them impossible to deliver consistent results with. With Vulkan there's more typing, but once you get something working it's going to work the same pretty much everywhere.

I kind of see it as a non-issue. It seems like Vulkan's target audience was specifically elite developers who wanted the most control possible, and based on the results which have been achieved in products like Doom 2016/Eternal it seems like it's working for them.

I suspect WebGPU will be the OpenGL successor for everyone working with graphics who isn't at an AAA game studio.

As I wrote above, OpenGL is an exeptionally bad counter example to Vulkan because it's just a massive soup of knobs and dials. D3D11 and Metal had this specific problem fixed already, and should have been used as base for an OpenGL successor instead of going all radical with Mantle.

Vulkan is basically a GPU-programming API with some support for triangle rendering, great for compute workloads, not so great for rendering triangles. At the very least, Khronos should provide additional layers on top of Vulkan to simplify traditional rendering tasks, basically providing one or more optional API layers that are closer to Metal and D3D11.

I would recommend watching some of the talks from around the time Vulkan was announced. The API was released very much in response to developer demand to just give them access to the GPU in an unopinionated way, and largely it has delivered on that promise.

Yeah I was around at the time. As I remember it, the "developer demand" was a very small but very vocal cabal of AAA game rendering engineers :)

I think the general idea was the right one, the execution of that idea was the problem (e.g. Metal is the successful execution of the same idea).

"Wiggle room" means, for example, that OpenGL drivers might look at the name of your executable to apply different hacks and profiles. It means that you write perfect code, and then who knows what will happen. Thanks, but no thanks.

Not what meant, besides, if you read NVIDIA and AMD driver release notes carefully, you will find that these also contain game-specific fixes in the Vulkan drivers. It's just rarer because there are not many games using Vulkan.
