I understood its otherway around, you use API front ver 10 or later on hardware feature level 9.3 or whatever. What I suggested was that for a change it might be Microsoft changed the implementation of the older code base (so that DX11 runs faster/better). But yea, they most probably wouldn’t. On the other hand if MS had grown itself even bigger like several other companies did before development would be even … staler its now.
Agile MS would change the OS kernel to freebsd or such and implement the Win32 API on top of it, and maybe a new modern API layer next to it that isn’t a numb way to lock developers in. That would be awesome.
Oh man its just to warm for humans here for a change, I have fever hallucinations.
