I re-ran the regression testing with Nvidia's latest beta driver (195.22), and i no longer suffer the FPS drop. I updated wine to v1.1.34 afterward, and the game (still) runs just fine.
I am gonna post to NVnews and ask if NVidia actually did something on their driver about that, or if it happens to be fixed "by accident".
Thank you guys for your help, ... and thanks again Henri for your patience and support.
