I've been vocal about the problems I've been having so I thought I would share my solution. You see the biggest problem is I want to play the damn game. I'm sitting here watching my wife play it on the 360 and it seems awesome. So I tried it on the pc, here are my general specs.
Intel I5 3.2 ghz
16gb DDR3
Nvid GTX 780 4gb DDR5
WIN7
Seagate HD (Non SSD)
For all intense and purposes my machine is a computing god. After all, it is one of the 300 steam machines. I should have no problem playing DAI at any setting. Except, I do. Stuttering, choppy, CTD's, the whole bit. A frame rate that looks like it's hand drawn, I can't win. The thing that gave me the biggest clue was, that no matter what the settings, ULTRA or LOW, it behaved the same way.
Way back in DOS days when programs wouldn't run you would turn things off till they did. So here is what I did.
Disable Origin in game.
Moved the game to the standard HD off the SSD, error checked.
MSCONFIG. I turned off everything but the AV, Nvid drivers, and Spybot Search and destroy.
Under the MS services I killed everything that didn't seem vital.
It was an improvement after this, but still not playable. After about 4 hours of game play I started tinkering some more.
I started killing processes, the big offender seemed to be the Windows Media Sharing Center. I had to kill the process, stop the service, then wait for the process to come back up, and kill it then it stayed dead. I ended any service that seemed unnecessary.
Run DAI
Better but still only with every graphics option turned off.
Rebooted, killed everything by hand again.
This time when I started DAI I right clicked on the service and gave it a high priority.
Bingo.
Running it in ULTRA not so much as a hiccup. I pretty much can't use my computer for anything else like this (internet and all the Google related services are killed) but I can play it. It is a much better game when it isn't stuttering every ten seconds. Still though, to have to do all this to play a game I payed 60 bucks for, I feel like Bioware should pay me some money.
If this helps anyone else, great, if none of it makes sense, and its the equivalent of standing on your head and wishing angels to fix it, well I feel your pain. So far though, I've played it for 12 hours without any trouble. Good luck everyone, I hate to say it,. but the game is kinda worth it, some truly EPIC moments worthy of DA.
