from the start to getting back to playing took like 30 minutes. I hope it works for you!
how long did it take to do that? I might try that tonight
I was having major lag issues on my ps3 with this game, so I tried rebuilding the database and restoring file system on my ps3, then deleting the gta v installation and then re-installing it. And it has completely fixed the problem and I am getting a smooth 25-30 fps now.
Just google how to do it, it easy very and only takes minutes, and doesn't delete your data.
Did all your savefiles stay or did they get deleted?
