I am sorry, Arisme, but there is no speed improvement what-so-ever in the latest build. The cutscenes play at about 2-3 fps. The sound is perfect though, but the picture can't keep up.
Also, the sceen where you use the canon, right from the beginning, is almost to slow to be playabe.
But like Marconelly said, screen shaking is gone, and it doesn't longer prompt for key assignment more than once. (Although zoom-functions do not work).
I was thinking of upgrading to wm2003 again tonight, and I will se if there is any difference there.
Hope I can help somehow.
