I bought the GOG version and it does run at the correct speed. It's not what the whole thing is about. Here:
http://www.gog.com/en/forum/commandos/behind_enemy_lines_doesn_amp_039_t_start It's all there. Topic is marked as solved, but using 3rd party program to run the game in windowed mode without the possibility to maximize it is hardly a solution to me. Playing the game in a small window and having to watch my desktop in the meantime kinda spoils the whole experience. I wouldn't be so frustrated if someone from GOG team at least told me that the problem is going to be addressed, that someone is working on it.
Skreczi Hi, I haven't send anything, sorry. I was under the impression that someone from your team read this topic above and is aware of the problem.
