So I have to start over? Because I saved quite a few times already so I have to start a new playthrough now?
It might be worth backing up your save folder and trying to prune out all but the latest save file. But make sure to back it up! I seem to recall there being an index file of sorts that tracks all the saves, and the game might not be happy if the actual save files aren't also there.
In terms of what I'd do, step by step:
- Back up the save folder. (%localappdata%/carnal_instinct/Saved/SaveGames)
- Load up the game, and delete all but your latest save using the save/load menu.
- Go to the save folder, and delete the files for the saves you deleted from the save menu.
- Load up the game again, and see if this has improved stability/performance.
I've personally never run into this issue (I don't save often), but from the reports it seems to be tied to how many files the game needs to dig through in the save folder. This is not a guaranteed fix - as I said before, the only thing I've seen that is, is not making many saves in the first place.
