Also note that OpenGL support is on its (slow and very long) way out of Qt: https://www.qt.io/blog/qt-5.14-has-released The plan is to go with the more "native" lower level newer APIs like Vulkan, Metal etc.
The move is mostly to support multiple APIs instead of only OpenGL. There are more details here: https://www.qt.io/blog/qt-quick-on-vulkan-metal-direct3d
Thanks for the link.
Or are you concerned about the lack of feature by feature compatibility with x86?
IMO, having less differences between architectures is generally better.
that is a valid concern then I think, and if it makes any life easier we should align. :-) But the alignment could be by changing x86 to the more modern 3D apis .. although I don't know how painful that is going to be.
We need to support this new API anyway, not sure if we could support both for some time.
If you mean RHI, it has full OpenGL ES support.
Fabian, you may have a clue?
The option is to switch between OpenGL and OpenGL ES, it has no impact on Vulkan support. Many mobile GPUs have better/faster/higher OpenGL ES support than OpenGL, so I'm against switching. The RPi for instance does not do OpenGL well at all. Apart from fixing some build issues, are there other advantages? Cheers, Fabian
Cheers, Guillaume
