i commit this from my VM that i still havent setup a GPG key on because when i tried it made git segfault

[Beyley]

Hmmm it seems this would make D3D11 have a hard dependency on D3D12, how is a way to go about this while still keeping the API good, if i put it into a Silk extension would the VTable extension methods still work?

[Beyley]

Builds locally on my machine now as an extension

[Perksey]

Where does the extension come from?

[Perksey]

Oh nvm I see it, yeah this seems sensible.

CI hit an OOM, restarting
