OpenGL has been deprecated on everything but Android, Windows, Linux, and PS4. Vulkan is the new open standard modeled after Metal (macos, ios) and DirectX 12 (windows,xbox). Vulkan, like Metal and DX12, offer direct memory access to GPU resources. Modern OpenGL (buffers and vao’s) is close to what vulkan is but vulkan takes it further. With command queues for multithreaded rendering and everything is a buffer. Indices, vertices, shader uniforms, everything. WebGPU (wgpu) is another abstraction on top of all of them that I feel is the modern bgfx, that is, a modern abstraction of those buffers and queues that work across DX12, Metal, and Vulkan. If you aren’t in the graphics space, I would skip learning vulkan and learn webgpu wgpu-native.

OpenGL has never ever been used on PS4, it has always been a custom API. Unless you're talking homebrew stuff. Vulkan was modeled after Mantle, AMD's own API that was basically what was available on consoles but less specific (ie. supporting more than a few custom GPUs). Direct3D 12 was modeled after consoles and Mantle, just like Vulkan. Same for Metal, that was made available in 2014, same year D3D12 was publicly announced. https://en.wikipedia.org/wiki/Mantle_(API) https://en.wikipedia.org/wiki/Mantle_(API) https://twitter.com/repi/status/446718535616585730 https://twitter.com/repi/status/446718535616585730

  Yeah for PS4 OpenGL worked but wasn’t their API, they have GNM. Yes but they all have a similar design around treating the GPU as a buffer store. You’re right about Mantle but that was the inspiration of many. They each took some concepts. I’m not an expert on driving decisions behind them. Just from my own experience. Vulkan is much more difficult and verbose than the others. This is one of the main hurtles to Vulkan.
