It's odd you mention this. I've been wondering about this myself but strangely not in the case of CloD.
I also have some games that show the same behavior. Guess I'll have to do some research on the web - usually I thought it's the fault of the game but it could also be a Steam issue or something with the redistributable packages not being installed properly.
Maybe it's linked to this:

I will try it out later if I find the game that had those issues.
