Which graphics driver is recommended?

[Radiant]

For distributing a game with maximum compatibility under Windows systems, which graphics driver would you suggest as the default/initial value in the setup? Is this Direct3D or OpenGL or SDL2?

[Crimson Wizard]

The one named "SDL2 software renderer" is the... software renderer, formerly known as "DirectDraw5". It's the slowest from all, but may be used in case others failed, as SDL2 will try to create an available output (which may be direct3d, opengl, and few others).

But I cannot answer the rest, which one of Direct3D or OpenGL to choose from. In the past Direct3D seemed to work better on Windows, but this is not necessarily the case after Win10, as D3D9 is a legacy driver and is supported only through some kind of an emulation.

We definitely should add a contemporary DirectX renderer (11 or 12).
