Before I consider buying this, could an owner of the GOG version please confirm that the screen shake (as well as all flashing effects that may exist (?)) can be completely turned off?

I saw a gameplay video where the game shook on almost all user actions (which to me personally seems to be quite off for this type of game).

Thank you very much in advance!!

[Edit: Note to GOG staff; please let me activate the "mark as a question" button even after I submit a topic ... sound good?]
