1. Both my created games and built in campaign are running real sluggish. The screen kind of flickers like my processor isnt good enough. I checked and it is compatible....Any one have any advice?
2. Im having trouble with the script editor and I have no clue when it comes to setting up conversations...any advice would be appreciated.
3.How do you set up the transitions from one area to another (i.e going through a doors).
4. Where can I find a comprehensive list of gods and the other divinities?

Whoever helps me with this problem will get my eternal gratitude and a lifetime supply of gummy worms.....alright, all I can afford is the gratitude....

I can't really help with the screen flicker, but I am sure a more technical person around here could, if you provided more detailed system info.
