Thank you very much for this.
I have a ATI, RadeonHD2600 and I'm getting random crashes you mentioned the sky, I'm going to try to set it to hide the sky in the config to see if that helps.
Is there anything else we can do to help you guys fix the bugs?
One minor thing, I can escape the NGD intro movie.
Disabling the sky didn't help.
