I noticed you have a laptop computer and it has both Intel and nvidia cards....don't know if this will help at all but....
I have seen two issues come about with other games with this setup, first is related to power management believe it or not. The power settings on some laptops dictate that when power drops to a certain point, then the onboard Intel card starts being used to help the Nvidia card and this can cause crashes and other issues. To fix this you had to go into your power management settings for the laptop and make sure everything was set to performance and such so it used the best no matter what the situation on power was...and keeping the system plugged up during play also helped.
The second issue related to drivers for the vid card, and them just not liking ones NOT put out by the computer manufacturer...this of course meant that the only ones that worked well were several generations behind what was being released by Nvidia directly because you had to wait for your manufacturer to get around to updating theirs to fit their machine and they seemed to not want to spend the time doing this after the machine aged a bit.
And you don't have 16 Gigs of ram for Video which is what this is talking about...your DX file shows you have 1961 MB of dedicated video memory and 8143 shared video memory. So depending on what is going on with the shared memory and if anything else is using your video memory, you may actually be running too low on memory to do what is needed when trying to play the game.
1 GB of memory is 1024 MB so you actually have just under 2 GB of dedicated memory.
