I've been doing some testing on the PS3 lag issue. This includes several methods talked about here on the forums, including using a PS3 with a solid state drive installed, a 7200 rpm HDD installed, turning auto saves off, using hdmi (which would astound me if that truly had something to do with it) over component, and various other "theories." I've received several saves ranging from 3.5 to 12 mb. I'm especially looking for anyone who is experiencing incredible, game breaking bugs and lag. The sooner it occurs in your playthrough, the better. I've also been looking at the XBOX and PC versions (I work with a lot of Elder Scrolls fans) to see if this is only related to the PS3, or if it just happens sooner in that version of the game. There is no doubt that in all versions, the game saves grow constantly, and at an alarming rate. It seems to have something to do with the persistant world being created by the game engine. Especially with the cleared dungeons.
