Guys, I really need some help here. As a die-hard Demon's Souls fan I was so excited to get Dark Souls. I put well over 600 hours in Demon's Souls and already about 60 in Dark Souls but that damn stage is preventing me from having fun. My main problem is the framerate which must be some kind of inside joke to make the stage even more disgusting. How long is this fucking stage (atm I'm at some kind of water wheel)? Are the next stages as bad as this one when it comes to framerate issues? Any tips how to quickly finish this stupid stage?
If you're on the floor of Blighttown, position yourself to have the bonfire at your back. You have to go to your right, pass by the wheel and continue, until you can see a hilly kinda thing, with trees stucking out of it. There are some fatties in the area -- you can go around them.
Middle-top of the hilly thing is the entrance to Queelag, the boss for that stage. Beat her, and explore the area after her.
After that, if you want to get out of Blighttown the fast way, go up the waterwheel you passed by earlier, and then continue to go up up up. At some point you'll come to a path, with 3 fatties, and the exit. It will lead you into Valley of the Drakes, right across a gate which lets you enter New Londo ruins, leaving you right next to the elevator that leads you to Firelink Shrine.
Running this path (instead of fighting your way through it) will take less then 3 minutes going from Queelag to Firelink.
Blighttown is, I think, the worst when it comes to framerate. Nothing after is as bad as Blighttown.
/edit
I think you'll need a key for the gate you find in Valley of the Drakes, but if I remember correctly you should find the key when you get to the top floor / path towards exit, right before those 3 fatties I was mentioning earlier. However, if someone can confirm this, it would be great (I cannot right now).
