Wasn't really planning to register on the forum, but I also have had a lot of these DEP crashes, and I think I've fixed it in my case.
Like most others, the crashes were rare at the beginning, but got worse later on in the game. I got to Ellinia and the crashes made the game almost unplayable. I think I tried every single solution the forum offered except for turning DEP completely off.
When billharris44 mentioned the event viewer, I figured I might as well check, and I found the faulting module to be named nvd3dum.dll.
I googled it, and found it to be related to Nvidia drivers.
So I did a complete uninstall of drivers (had quite a few on top of each other), installed the newest driver and tried the game.
I've played the game for several hours now, through many long battles, and the game hasn't crashed. I got some problem with flickering light, but I turned of antialiasing and it disappeared.
This probably won't help everyone. I think a patch is needed, but maybe this can help those who just install drivers on top of old ones (like me).
It seems pretty much everyone with the problem have a nvidia card.
If you check the event viewer and see something to do with nvd, then it's probably the drivers messing things up.
Some events were marked as unknown however so I might get a few crashes later. As long as it's only once in a while, and not every single battle, I'm happy.
Now I'll try to actually finish the game. I will probably start again for the third time since my mage is pretty bad. Got a little unlucky with the map, and weren't as good at planning so maybe I'll try again with my greater knowledge.
