The meaning of the CRF values has changed many times in the history of x264. Therefore you cannot expect that a specific CRF value still has the same meaning in the "new" that it had in the "old" version.
Also, how do you know the "new" version is performing worse than the "old" version? Did you actually compare the resulting files
visually? Or how did you come to the conclusion that the "new" version has a problem?
(Of course you can only compare file of the same file size, otherwise you are comparing apples and oranges. Thus, if necessary, adjust the CRF value so that both versions produce a file of the same size)
