There is still older hardware around which does not support vulcan. I can tell you, that there are even devies around which would be considered “ancient”.
afaik, the kronos group is not intending to drop OpenGL. Maybe apple does, because apple is giving a f. … but tbh I dropped apple anyway years ago and stopped delivering to it for a couple reasons, so I can’t tell about them - everyone else will still keep opengl at least as a legacy API (and be it just a layer on top of vulcan) - otherwise millions of older apps would stop working and that’s something noone wants
While I agree with you in principle, I am coming to the conclusion that the powers that be will drop support for OpenGL completely very soon.
Khronos are pushing Vulkan
Apple don’t give a &&%£%^ and will happily drop it overnight without telling anyone first.
Microsoft will probably not support it, but not block people from using it.
Linux … don’t know , don’t care
Android … probably will drop it in favour of Vulkan and again I doubt you will have backward compatibility as that will increase OS image size
It comes down to a (probably off topic) question of how many users we believe will be able to run OpenGL apps in six months time
I am not preaching, I am asking what people think.
Vulkan is more a GPU API than a GFX Api … there is no reason why there should be no OpenGL Interface available which just sit’s on top Vulkan (as XNA or Monogame juts sits on top of DX). So there isn’t a lot what the manufacturers can (or have to) do.
MS don’t care anyway, because it’s up to the driver developers of GPUs what interface they support.
So personally I don’t think OpenGL (as how to access GFX) will not die very soon. That said - I still would love to have Geometry Shaders available, as this becomes a more and more common feature in modern games tbh
