Proprietary for now, not sure how good the open source one is. But the proprietary has many quirks/bugs and limitations especially when i comes to things like Linux specific Vulkan extensions.
I don't know the full story, but afaik, AMD/Intel Mesa based drivers are fully open source and are built in a much more Linux-native way. But unfortunately hardware choice is out of my jurisdiction.
I’ve run the open kernel module for some time and it seems to work well although I had to patch it to fix support for some VR hardware until upstream fixes it properly. What Vulcan extensions were you having issues with?
