While you don't say what your question should be compared against, it is generally reported that DX12 performs quite a lot worse than DX11 in BF V.
FPS are all over the place using DX12, compared to DX11 - which doesn't even perform well either when it comes to BF V.
Adding RayTracing makes it even worse.
But without knowing what you want us to compare it to, DX12 may run incredibly well, compared to whatever you are thinking of
EDIT:
Personally, I prefer DX11 over DX12, for the best and most smooth BF V gaming experience.
