Hello,
The only suggestion I can give in this matter is to compare performance
with tools that already support both OGL and DX.
I hope I'm not a sinner mentioning OGRE. I'm not familiar with OGRE but
if someone knows that library as well as OSG, it is possible to build a
set of programs

disastrous for all non-Microsoft platforms.

CAD apps favour OpenGL? If DX can't do multiple windows/contexts nicely
