So far, sadly you have to install the Polish dialogs to be able to have enough time to read the full dialogs, there seems no way to even pause and read. I am using the Optimized version and I am still losing much dialog cause I can't read it fast enough. Not to mention being force to Speed read like that takes you out of the gameworld, well it does for me anyway. Oh iirc you might have to add the Polish Voice Animations as well so the Lip Syncronation works.
