I think it is related or at the very least has something to do with the memory in the ps3 and how the game uses it during gaming. I personally think the ps3 doesn't have enough memory for this game but if its not that it could just be the game isn't optimized to run on the ps3's small internal memory. Memory and don't get that confused with hard drive or hard drive space, can have a big effect on anything, it can cause errors, crashing, freezing, etc. If I were the one to be tasked with fixing this freezing problem I would start looking there.
I have the 120gb slim ps3 and it seems the only time it will freeze during gaming is after several hours or loading a lot of big places like the strip or the more populated areas.
As much as I hate to admit it, I am thinking you are right.
My friend's new PS3 is the 160gb with the supposed "new wider and better" heat sink ... according to him ... and the game seems to be running flawlessly.
Still, as I said, the game ran flawlessly for me on my first gen 60gb for like 65 hours of play.
The whole situation is just strange.
I guess I really don't know enough about software design and computers to make sense out of this. All I know is that this is the first PS3 game that I have seen which freezes and crashes the way it does. Also, I've never heard of a game with such diverse behaviour. By that I mean ... it reacts differently on the PS3. The fact that there are those (my friend included) who have no problems at all ... well, it's just insanely strange.
To be very blunt and honest ... if I were not experiencing these constant random freezes and crashes myself, I wouldn't believe it.
I don't know what else to say. Right now, as I type this, I am watching my friend make his way to Primm.
It's been over an hour and he has had no freezes or crashes. There have been a few "bugs" with Geckos being caught in rocks and stuff but nothing major.
I just don't get it.
I don't understand how this game can be so different for so many different players.
