mogilnik: I feel a slight lag too. The cutscenes also seem a bit choppy, the opening one where the camera pans over the sea for example - it's not as smooth as I expected. Like if FPS dropped badly (which could just be the case).
I wonder if it's related to the bug in the first game where the train maze would fail on "slow CPUs". Which apparently also includes my Core2 Duo @ 2.4GHz.
However, other than the few places where the audio seemed to lag in Deponia 2 (tutorial, of all things), the game seems to work well in 1920x1080. The dialogue between Rufus, Goal and Cletus in the capsule did feel weird though. It's like every time the camera POV changed, and the game loaded a different background for the talking character, there would be a slight delay. I attributed that to the lag problem as well.
Is there an official statement on what the game minimal system requirements are?
