Neither is inherently better. It depends on what you need. Vulkan gives you more control which can be beneficial for advanced rendering techniques however comes at the cost of requiring more knowledge to use. OpenGL is simpler but generally has higher driver overhead.
whats metal
It’s macOS’s graphics API, like how Windows has DirectX and Linux has Vulkan.
Afaik, its Apples way to render things with their OS. It only works with Apple and its similar to DirectX which only works for Windows.
The best thing everyone should use is something that supports all platforms like OpenGL or Vulkan which is even Open Source
opemgl vs vulkan whays better?
In this case probably Vulkan, as developers tend to use current computers which support Vulkan, which is faster and younger and has less overhead.
In other cases you probably want OpenGL because older GPUs don’t support Vulkan and usually you want to include as many users as possible.
