Microsoft's Mesa D3D12 Driver Now Allows OpenGL 4.2

[Doug]

yep, seems to be working nicely

OpenGL 4.2 is exposed atop this driver that in turn will run atop Windows' Direct3D 12 drivers whether it be for lack of native OpenGL drivers or if running by way of Windows Subsystem for Linux.

Do I understand that correctly? This is not only for WSL, this is intended to also work on native windows? This would significantly improve the sad state of OpenGL on windows systems.

if it preforms well, but you can also use zink on windows, I dunno how well it works

Yes, I believe so. However, I'm not sure it's really an improvement for most people who have native Intel, AMD, or NVidia drivers. It would be helpful for ARM windows devices, though, which don't allow native GL drivers.

I repeat myself but calling an OpenGl driver "d3d12" is really stupid and confusing.,.

Isn't d3d12 the driver that outputs code for the D3D12 API, and the OGL part just a subset of it (using Mesa's OGL)?

It is more of a windows SDK issue. If you develop on windows with OpenGL (which I happen to do), you're pretty much limited to OpenGL 1.2. For anything else you need to go through a toolkit (GLEW, GLUT, Qt, GLT, SDL etc). I would certainly welcome if this would trigger microsoft to put support into their own SDK's.

This would be amazing to use in RetroArch instead of ANGLE for higher OpenGL support on Xbox One/Series Consoles and Dozen when ready will also be a great addition. I have opened a bounty on retroarch’s GitHub if anyone wants to try replacing ANGLE with this
