The profile that comes with vorpX is OpenGL only. Versions prior to patch 1.29 supported OpenGL by calling ‘wc3.exe’ with the ‘-opengl’ command line option (without the quotes). For 1.29 and above that apparently was changed to ‘-graphicsapi OpenGL2’.
Caveat: I’m not sure wether the profile still works with 1.29+.
BTW: IIRC they also changed rge D3D renderer from D3D8 to D3D9 at some point. No promises, but I’ll check whether maybe a D3D9 profile is possible and let you know in a few days.
