On my system, the loading times for all missions are very quick. However, the downside to this is that the character profiles that accompany some of these load times disappear too quickly to be read. I managed to screen capture the first few of these profiles for my own use, and thought that maybe a small minority who haven't done the same would also like to see these.
I hope these won't be a spoiler to anyone, considering that these characters are available very early in the game:

Thank you very much!

wow this is awesome! Loading screens didn't display that long on my comp either.
Now I know why some of the guys seem so wacked. :P

Might want to check if your CPU's affinity for the game's process is set to only one core (CPU 0, for instance). You can do this in the Task Manager, through he Set Affinity option. Old games can sometimes go all wacko on multi-core systems.

Thank you! The loading screens flash up for about one second on my system.
