With 2.0 yesterday I introduced an issue with the HUD modifications. I fixed it now. That’s all that has changed.
People are also reporting some stability problems and physics issues since the patch, but I’m not sure those are related to DSfix. On the bright side, it seems like in addition to fixing the stereo downmix, the patch also somewhat reduced the CPU load of the game.
Edit: Mediafire decided to take the file down for some reason, here is a mirror.
You can also always get DSfix at the Dark Souls Nexus.
