To get 60fps in your game, all you currently need is Durante's DSfix. This was not always the case, and is the reason this video exists. Download it here, and read the README! ---If you can't be bothered to read the README, all you need to do is drag all the files you download into the same Dark Souls folder as your DarkSouls.exe file is located (the .exe that launches the game). Then go to the dsfix.ini file, and change the fps from 30 to 60. Save and open your game. Some areas work better than others, and you will rarely get a stable 60fps. Powerful CPU is required.
