And after reading the forums for more info on the subject, I've decided to try something, hoping to resolve/improve the manner.
So what I've try is to disable the Auto-save functions for the ''save on'' menu, fast travel and wait options in the settings menu. (Remember to manually save whenever you can before big fight or after quests completion)
I've played for about an hour, fast travelling from Town to town and dungeon to dungeon. And after a few Civil War quests and a few moderate scale battle, my game was still running super smooth. (with a few very minor frame drops)
I tried this on a slim version of the PS3(1st Gen), with a save file of 9.1mb in size.
Now I'll try to play for a few hours to see how this thing turn outs.
Hope this might help a few of us.
p.s: Im not trolling, this seems to help my game, so I figure that if It could help me it could help others.
