Dude, I've been here since day one of the game. I catalogued the issue and was the first person to tie actions taken (quests, dungeon delving, exploring new town, dragons) to the game problem. Here's a thread I made on November 19th, just 8 days after the release: It's entitled, "Only certain actions increase the save file" http://www.gamesas.com/topic/1281304-only-certain-actions-increase-the-save-file/page__fromsearch__1 The save file serves as a sort of canary for the problem. Rapid increase in save file = rapid increase in memory consumption.
The 1.4 patch is the FIRST patch that actually solved the problem for most of us.
If your system is still having trouble, then we need to figure out why. Perhaps your hdd needs defragmented (do you play a lot of demos on it?), perhaps space needs to be cleared out (I'd recommend at least 10GB to always have around on your ps3), perhaps there's something else that you haven't deleted yet?
That being said, I've noticed some problems people are having with starting a completley new game. I wonder if they didn't introduce a problem with that? Maybe first time players of the game should follow similar steps to people who have been playing the game. Because patch 1.4 IS still rewriting code. If we had to load an existing game, save, reload, wait, save again then maybe new characters need to do something similar or the patch causes issues...?
Excuse me if my last comment was a bit hard. It's due to frustration and I hope you can understand me.
I'm not having any problems with my other games, I don't play demos and my disk space is about 190 Gb.
The last night I lost a lot of progress because again my game froze and I dare not turn on auto save because Bethesda has not ruled on the matter.
My situation is: I don't feel comfortable with the game because I do not know at what point it will freeze wasting my progress and having to reboot again.
It's not my system, it's due to a broken game.
