Valve: Steam’d Penguins

I suppose that Microsoft had no choice but to back off their efforts to undermine OpenGL support on Windows in part because they failed to convince some of the major CAD vendors to port to DirectX. After all, what is the point of supporting two different 3D backends when you don't have to? Much of high end CAD still runs on Unix workstations. There is no way the CAD vendors would have left those guys in the lurch.
