So after looking around for some time I have discovered that the issues I am facing may perhaps be related only to mobile GPUs.
People in this REDDIT posting...
http://www.reddit.com/r/DivinityOri...d_performance_on_my_computer_any_advice/... stated that they were getting more performance from their integrated 4000 series Intel cards than better Nvidia mobile cards. They also made reference to this post...

... which stated that the game has been optimized with 4000 series Intel integrated GPUs in mind...
I would greatly appreciate an official response from a dev in this post with affirmation that optimization for mobility cards is coming soon. Please read this and comment. I implore you. I've been dealing with rollercoaster frame rates ever since buying this game and it would make me feel a lot better knowing a developer was aware of my issue. I have sent a support ticket but no response has come in the last three days. I know you all are busy with patches but if you could take a moment to at least comment of the issue.
I'll bump this post again tomorrow with any new information I find on the issue.
