It's probably due to a change that you might have made on nvidia settings, like fixing Anisotropic filter or some other. I would try reinstalling the drivers using custom -> Clean install
I updated both my graphics driver and 3dmark to the latest version and that did the trick. Voilá!

Defiance V 17" / i7-8750H / RTX 2080 Max-Q | 16631 | 21280 | 14033 | 62° | Link |
A pretty decent score IMO. The talk about Max-Q just being screwing customers, doesn't hold up to scrutiny. Much the same as the full 2070, but cheaper, if I recall correctly.
