OK, so after 4 hours with tech support on the phone and many many tests (thanks guys!) it is indeed a conflict between Inquisition and some other program on Windows, from what I can tell audio related.
I ran Task Manager (ctrl +shift+ esc) and went to process tab and the System (NT Kernel & System) started using processes when Inquisition booted up and at no other time. Task Manager isnt specific, and so I finally had to download a program from microsoft to monito all usage, and narrowed down an audio driver that was trying to be used, even though it shouldnt be.
In an effort to see if I could fix it I deleted my old audio drivers completely and lo and behold Inquisition is now working perfectly, and there is no freezing or stuttering.
Note: If you just delete your audio drivers, you will have no sound, unless you have a USB sound card just laying around like I did.
So in conclusion:
Check Task Manager for a non critical program conflict with DAI
If it is a critical program conflict (system), check your audio drivers.
