I _just_ moved from Windows 11 to Kubuntu. None of that stuff is missing. In fact, unlike Windows 10/11, I didn't even have to install a graphics driver. My AMD 7700 XTX literally just worked right out of the box. Instantly. Ironically that’s not the case for Windows 10/11. This isn’t a “My OS is better than your OS” debate — we’re talking about why D3D being integrated into the kernel is a good idea. I’m playing devil’s advocate.
And thus, you missed my point: "Why should Linux have an equivalent to Direct3D" isn't me arguing that Windows having it is bad, it's me asking people to think about design choices and consider whether they're good or bad.
> This is far better than Linux's (neckbeards'?) philosophy of Thou Shalt Not Divert From The One True Path which will inevitably inconvenience many people and lead to, you guessed it, failure in the mainstream market.
If you think Windows having Direct3D "built in" is why it has mainstream dominance, then you potentially have a very narrow view of history, market timing, economics, politics, and a whole range of other topics that actually led to the dominance of Windows.
