Chances are that The Witcher EE has no other DRM.
I'd only wish developers and distributors did not make it so effing hard to find out the real limitations attached to their products. Now we are left to dig and dig for it, and then infer the truth from what they don't say. And then there is the occasional lie. (Yep, I'm looking at you, "we removed activation from Bioshock!" 2K Games.)
It only takes one line of text to identify and/or describe any DRM scheme currently on the market. That line of text should sit right on the official Tech Specs page (several lines if there are different versions of the game). The one-page "What is...?" FAQ/summary of a download service should contain "the XYZ client needs network connection each time you install the game", if that is the case. 
And if your game does not have DRM? If it does not have network activation? Please, *please* say that in writing. Even small niche titles get infested these days. If you say nothing, I'm going hunt for the information from a 3rd party, that may or may not be reliable. Maybe I won't find that information at all. Either way, there is a real chance I will just forget it.
