Firstly, nVidia Control Panel; Manage 3D Settings> Program Settings Tab. Locate or Add PUBG (Steam>Steamapps>Common>PUBG>TslGame>Binaries>Win64) and set Power Management Mode to "Prefer Maximum Performance". While you're there turn "Threaded Optimization" on, and see if that helps any.
Secondly, double-check and see how your CPU is behaving during those drops. Ensure it's not downclocking at all with HWInfo or something.
Otherwise, It's just a case of waiting for further patches. The game is early-access, so it's likely it'd still perform better on slightly older hardware than new stuff, you're not alone with the issues though, and I can only hope the suggestions alleviate it even a little.
Even so, I'll guarantee you're getting a smoother experience than I was with the Thuban.
Best of luck.
