Yes, they use opengl, but, doesn't software render use directx for rendering all the stuff? or even opengl stuff could be affected?

AFAIK, the only thing DirectX gives to software renderer is the possibility of using 32-bits textures. If any shit happen, vid_hw2d 0 will fix, in theory.

I thought the scene was just rendered by the CPU and the frame + HUD elements drawn onto the screen via DirectX. I don't think DX12 will affect any functions as basic as that.

Oh yeah, you are right, pardon for my misconception: http://zdoom.org/wiki/CVARs:Display#vid_hw2d
If false, this disables hardware assistance for the 2D layer when using the Direct3D renderer. However, hardware rendering is still used to get the data to the screen, contrarily to vid_forceddraw.

Honestly, it won't matter. According to the Compilation page on the wiki, the June 2010 version of the DirectX SDK is the last version to support DirectDraw, which ZDoom (and hence Zandronum) needs to compile, and therefore will forever be stuck at that version. This ultimately means that new changes will not affect ZDoom/Zan, for better or for worse.
