Hi,

So I decided to start playing Fallout 3 again. The game was already installed, I was just going to start from where I stopped last time, when everything went smoothly. However, I met some massive lag when I tried to play.

Not just when playing, but also the main menu. It kind of hangs for 0.5 seconds all the time, all the time from starting the game. I tried re-installing the game, and all removing all mods, but the lagging is still there. I have been looking for answers, but none of the ways I have found has worked for me. I did start a new save, and it runs very smoothly in the beginning. But when escaping Vault 101, when entering the Vault 101 atrium, and all places beyond that, the lagging appears again, also in the menus when pressing Esc.

I have updated some drivers, and my PC is without doubt good enough to run the game with the highest graphics options. I have Windows 7.

I tried starting the game at my old not-so-good laptop, and it runs smoothly without any problems.

I really want to play this amazing game again, but these problems are always in my way with these games :'(
