Maybe that can reduce a lot of work for supporting Vulkan？
Yes, it’s theoretically possible.
It would likely be less efficient and we probably wouldn’t be able to support all features of the graphics card, only those supported by Diligent/bgfx.
But it’s certainly possible. Are you willing to write such a back-end?
I am a newbie.
But, of course I would like to learn how to do it if there were tutorials.
