Vulcan API spec is out there now and is looking to directly compete with the DirectX api for gaming (and others), for Linux and other platforms.
I’m sure there will be a lot of discussion about porting from DirectX and/or OpenGLcode to the Vulcan API, so I’ll be adding more content here as I discover more about it.
update: apparently some are calling it vulcun api instead of vulcan. Learn to spell!
