Game freezes in Morgue

[tutike2000]

Hi, my game keeps freezing once I enter one of the rooms with a lot of bodies stacked up in a pool of water, in the Morgue.
I don't get any error message, ambient sounds keep playing but I cannot move nor look around

EDIT: it seems to be the room connected to the two body-filled rooms that's causing the problem. Game freezes about 30 seconds after entering it (it's the room that contains one of those 'jars' that you can use repeatedly to get a story fragment)

EDIT2: I've managed to get around this bug by switching to windowed mode and setting all details to low. Will try to narrow it down a bit more

EDIT3: Switching to windowed mode seems to be enough to avoid the freeze-up
