I also talked to multiple techs yesturday. Cool people. Anyway, the problem could not be solved but here are some things that could help:
Obviously after you fiddle with the graphics settings like turning off SSAO, etc. AS WELL AS closing all non-essential background programs
1. Control + r for run program. Type in msconfig. Under selective start up, uncheck Load Startup items then go to Services tab and check the 'Hide all microsoft services. Then Click disable all, apply and Okay. It will ask you to restart and go ahead and do that. Boot up the game and see if it works better.
2. Reinstall game, retry game.
3. Try playing the game under another User with Administrator rights.
4. Clear out Browser cache from beginning of time and retry the game.
5. Defragment your drive using Piriform Defraggler, then retry game.
None of these steps helped me but they could for you. Plus any technician is going to try and troubleshoot the problem by going through some of these with you anyway.
As for a patch, I am waiting for an official BIOWARE patch for DA:I and another NVIDIA driver update since the last one didn't work for me.
