Can OpenGL really speed up World of Warcraft III/World of Warcraft? (Only half of the text is displayed. problems such as cards are displayed)

Can OpenGL really speed up World of Warcraft III/World of Warcraft?
Reference:
By default, Warcraft III starts the d3d mode of dx8.1, but another mode is OpenGL 3D mode,
It is not that blizzard does not want to set it as the main model, but OpenGL is a professional 3D, with some graphics cards
This function is not yet supported or not fully supported. However, what I want to say is that this 3D mode actually displays more
Good, brighter, smoother, finer... and faster.
Users of either ATI or NVIDIA prefer the OpenGL mode,
The method is as follows:
Write "-OpenGL" in the desktop shortcut attributes ".
To test whether the graphics card supports OpenGL, use the [Warcraft graphics card testing tool] to test it,
Actual:
On my two computers, [World of Warcraft graphics card testing tool] The test score dx is half of OpenGL. Actually? DX is much faster than OpenGL!
I think I have a problem with my character?

Found: some computers use OpenGL, only half of the text is displayed, and some are very slow ......

Answer questions

In fact, if you think about it, if OpenGL is really suitable for World of Warcraft, Blizzard has already implemented it in the program. There are not many OpenGL games, but few. Just as assembly is very powerful and fast, not all software is written in assembly.
For example, the person who sells food is very fast, which does not mean he can solve functional analysis or artificial intelligence. Isn't it? The same is true for the World of Warcraft graphics card testing tool. Its Testing is very simple, but the actual combat is very complicated. Its Testing does not represent the actual combat.
As a matter of fact, Microsoft has already integrated similar memory optimization software into the kernel.
