Why is there no Directx on Linux and programs run slower?

Installed ubuntu mate. Uses 300 mb. Everything seems to be fine, but the unity program is running slowly. Much faster on Windows. Is it because of opengl? I also wanted to open the Nvidia settings, but on Linux they are somehow strange. There is also a bar in the middle of the browser. What's the catch? Is it possible to speed up programs that process 3d?
Why can't you download Directx? No craftsmen?

because directx is a collection of Windows APIs.
where do they come from in other systems?
there are exactly two options for using them:
1. translation into the means already existing on the target system. kind of like wine does.
2. implementation from scratch.
1 pulls the brakes and is not always possible.
2 is purely a matter of desire/time/money.

Because it is for Windows.

Sample 2010? Wangyu that the driver no longer supports this card.

Why you can't download Directx

Well, just a few points:
closed source code
Written specifically for windows
There are open source analogues (OpenGL, Vulcan) that are not tied to the OS

Video card: gt 425m

The video card will soon be 12 years old, besides, it is mobile and, probably, the developers simply did not import optimization for it (purely an assumption).

Because OpenGL is inherently flawed. DirectX is newer better documented and faster.
Well, it won't work on Linux. Maximum translation into something else.
