Well I had this problem too and apparently most of the RPG gamers have a habit of saving the game too many times... its more of a reflex that we try to save the game in a new/fresh slot before every conversation/interaction... I had this problem with witcher ages ago so i tried a similar fix and here is what worked for me.
The dragon age save file directory has the following files
DAISAVEAUTO<.....>.DAS
DAISAVECHAP<.....>.DAS
DAISAVEQUICK<.....>.DAS
...
...
...
.
ProfleOptions
ProfileOptions_profle
Of which the
ProfleOptions
ProfileOptions_profle
keeps our profile and gamesettings...
So everytime we save a game all the game details like time and space ... + the profile is saved i guess so it takes a huge space. The profile gets corrupted at some point i am not sure when because of this over head and machine limitations.
SO SIMPLY PUT- here is what you need to do:
1. Copy all saves to a new/different backup folder.
2. Delete all the files in the game save folder which is ..<C:\Users\[Username]\Documents\BioWare\Dragon Age Inquisition\Save>
3. Start the game. It should start just fine.
4. Optimize the settings . Graphics, sound and such.
5. Save settings and Quit the game.
6. Open the game save folder. Notice that the "ProfileOptions" and the "ProfileOptions_profile" are back ..... This is your new settings.... DO NOT DELETE IT.
7. Copy your save files ONLY from your backup. Do not copy the "ProfileOptions" and the "ProfileOptions_profile" files.
ALSO- it is advisable to copy only your auto save, quick save, Milestone and time files only.
8. Now Start the game .... Load your save point and enjoy.
BACK your saves periodically... Organize them categorically elsewhere and keep your Dai save folder clean..
May the maker walk with you...!!
