RudyLis: Thanks for reply. :) Your experience may be tied to your GTX card, as many Nvidia users do not have some issues us, AMD users have. But instead you have your own, meant to be played and such. :)
Jokes aside, so far I do enjoy game, and I can only hope CDPR had enough power, zeal, passion, muse, inspiration, whatever else there is, to keep game interesting throughout most of duration.
Well, judging by GUI/controls, we, PC users, got as much attention from developers as white crayon. :) Sad, really.
As for hairworks, I can't check them ingame, as FPS drop is too severe, and I'm not sure I'll be able to get decent look anyway.
P.S. Immortal Roach sounds like an awesome opponent for Unstoppable Raid. :)

Wompoo: You can lower the AA for HairWorks from 8 to 4, that could grab you an additional 4 to 6 frames with it... file to edit is rendering.ini path C:\GOG Games\The Witcher 3 Wild Hunt\bin\config\base... line to change HairWorksAALevel=8
