I have a 670 GTX 3GB and I run all the vid settings at Ultra, Fade Touch and 4xMSAA. I still get the occasional freeze during a cut scene maybe every 7 - 8 hours I'd say. Bad code is the culprit and better video drivers are also needed.
Since I have played many action and real rpg's, baldur's gate series, dungeon siege series, elder scrolls series and skyrim, diablo series, DAO, and DA2, among many others I can't remember, I would say, DA:I is watered down and not the quality as DAO and other RPG's. Its not a bad game, fantastic graphics and long cut scenes if that sort of thing floats your boat, but the excellent plots, story lines, useful side quests, intelligent skill trees and inventory system, chest, campsite, being able to chat with party members, etc, etc, etc, are not present in DA:I for some reason. This has taken away from DA:I and what could of made it a great RPG, truly best game and RPG of 2014 would of been the case then. But as it stands, its a mediocre game with many bugs and very limited to what you can do and very hack and slash.
There was a reason DA:I and the digital deluxe went on sale after release for only $45 CAD for me, because sales were hurting, but why if its the best game of 2014 and best RPG?!
I expect with Patch 3 and beyond, and DLC's, these issues to be addressed and bugs fixed, stabilizing the game, and proper optimization for the PC like they stated from the beginning......
I suppose if I just bought a PS4, never played the Dragon Age games before or real rpg's, then I too would say its a fantastic game because I honestly wouldn't of known any better.
