Could maybe setting the games affinity be a better solution, as in this - http://www.gamespot.com/forums/pc-mac-discussion-1000004/permanent-core-affinity-setting-for-steam-games-28868679/
I too am crashing as soon as I get past the startup vids. It seems like the game tries to change resolution and then I get the error. It's odd because I didn't have a single issue during the beta, and the game worked for the first hour or 2 yesterday. Now I'm crashing constantly.
Here are my specs:
Intel Core i5 3570k
Geforce GTX 670 FTW
12GB RAM
240GB SSD
For what it's worth, I had the same exact experience when I bought BF4. The game worked the first play session, and then crashed anytime I tried to run in afterwords.
