This is sad, my current 48 hour save file was so laggy that starting a new game was more fun.
Just sayin....
Oh and its lag free aswell

Haha yeah but when you get futher along the game it's going to happen all over again.

The further you go, the worse it gets I take it. Doesn't matter if you save or not. Let's hope Bethesda fixes this real soon. As Pete said, "Hang in there".

I'm too scared to start a real serious game just in case the patch (if there is one) might bugger the save game up or only work for new games.

Yeah, I'm aware of that. But hey its better than not being able to walk at all =/
Yes, indeed Bethesda really needs to fix this lag problem. It's pretty unfair if they don't.

Yeah I just ditched a 58 hour playthrough on my PS3, playing on PC with ultra settings now (looks awesome). What a waste of $120.

Honestly, the happiness that comes with a total fix for this would far outweigh the shame for having to start another character.
