Hello.

I have noticed several threads about freezing on the first page alone, and it is an issue. A game should not freeze this often.
However, having the PC version aswell, I can tell you that the PS3 is more than capable of handling the game.
The PC version will run on my ten year old computer with a Pentium 4 Duel Core.

I see many "fixes" for the issue say to delete the data and don't keep saves. This is a bandaid fix and these are only an issue for when the PS3 doesn't clean up the game data when it's shut down by the button when the game freezes.
The main issue is that on processors with more than quad cores, it doesn't clear the memory correctly. There's a user-made mod for the PC that not only fixes this, but proves that this is the issue.
The PS3 has eight processors of about the same strength as the Intel i3. Seven of which are for the game, the eight is for the PSOS.

The only real way we can fix it is either wait for Bethesda to release a new patch, or to ask the PS3 jailbreak developers to make the game compatible with PC mods.
The latter being the quickest and most sure way.. On a related note, @devs, this is why jailbreaks are made.

Questions?
