Hello,

from the beginning, the game executes very slow and the mouse is stuttering.

What could I do to make it playable?

Update: I found out I can make it playable by not starting via the gog-installer desktop icon but starting DOSBox first and then entering the commands (or editing the BAT accordingly).

Although, while the game is running smoother, the controls for walking are very cumbersome and I decided to skip this game.
