Mission loading probs and crashes partially alleviated

[Iphigenia]

I'm playing on a low-end system and have been having intermittent probs with freezing during loading and crashes ("Launcher.exe has encountered a problem") issues during play.

After an hour or two experimenting with options I've concluded that the "visual effects" setting is highly dangerous to me. I can raise most other settings but if I move VE off 'low' crashes are inevitable.

Thought this might be useful to others in a similar boat.
