Just making sure here, you're on the PS3 right? From experience, I endured similar symptoms throughout most of Bethesda's RPGs. From what I can tell by playing Skyrim, an SSD would improve your overall gameplay experience with FO3.
Yeah I'm on a PS3, and I don't know what else to call it. On computers I'd call it mouselag, but yeah here I guess it's pointerlag? lol.
Update on getting the PS3 back up: I had to force a turn off by holding the power button for 20 seconds when it froze on the restore. Then it came back up claiming corruption so it reformatted. I then went to do the restore again, and this time it started up fine, but failed partway through. It rebooted itself and claimed corruption again, then reformatted again, but this time said it had recovered a bunch of stuff and put it under the same username but with a * in front of it.
It looks like it got my savegames, but not all of the game data or downloaded games I had.
For this reason I would probably suggest to anyone that the only things you use the backup/restore for are savegames or things you can't get again. Like delete your game data cause the discs will reload it, and delete downloaded games like the two we got for free during the PSN debacle, cause you can download them again for free.
Started up FO3 and it's attrocious at the moment but I chalk that up to the disc reloading the entirety of the gamedata in the background. Since I only had a fraction I went ahead and deleted it.
Wondering though if it would be better to plug in the old hdd, delete all that stuff, and do a different, smaller backup. Then put the SSD back in and try the restore again, seeing if I can get it clean.
Any thoughts on if that would work any better? I also don't know if you plug your old hdd back in if it asks you to format it, cause a new/different PS3 than your original would apparently.
