I came across this blog post on hackernews about the L4D2 port and it reminded me of a conversation here a while back about the unassailable position of DirectX in the gaming world.

Could be that Valve is going to turn that on its head. OpenGL port of L4D2 is running at 315 fps now versus the directx implementation at 270. Windows OpenGL itself is running at something like 303 fps.
