I'm starting to speed run and need tips/help on how to speedrun Dark Souls 1.

I have never played the game before and need some starter tips on how I'm suppose to play the game before i start playing so I don't pick up bad habbits.

My first question is what is best to use? Controller or Keyboard+mouse?

It says it has controller support, but I cant make it work, so is there something I have to do to make it work?

The best place is to ask this is on the Dark Souls 1 Forums, which are on the left hand side of the game page.

just from experience if you plan to run of PC definitely use a controller =)

Thanks for the help and suggestion :D

Actually the best resource in this case is the Speed Souls Discord server, and to a certain extent the Speed Souls website. In the Souls community, speedrun.com is kind of a secondary thing.
