nobody is saying it isn't.
the most likely reason is it using the 'borderless full-screen window' instead of an exclusive full-screen mode.
in those modes you seem to get additional lag from Windows *forcing* vsync, and some background window composition stuff.
a lot of games seem to be using that mode now tho unfortunately, wouldn't be surprised if the true full-screen modes end up being phased out by Microsoft which will certainly be a problem.
