alt Hacker NewsOn the contrary, I would say this is the main thing Vulkan got wrong and the main reason whe the API is so bad. Desktop and mobile are way too different for a uniform rendering API. They should be two different flavours with a common denominator. OpenGL and OpenGL ES were much better in that regard.
It is unreasonable to expect to run the same graphics code on desktop GPUs and mobile ones: mobile applications have to render something less expensive that doesn't exceed the limited capabilities of a low-power device with slow memory.
The different, separate engine variants for mobile and desktop users, on the other hand, can be based on the same graphics API; they'll just use different features from it in addition to having different algorithms and architecture.
