This post and the implementation is wrong. It will be fixed in the next release.
You will have the option to use either. Also I agree this is not BPM-relative, which is why I changed the wording. Please see cutting edge build.I understand the change in wording, but I still don't understand keeping the old system. Of course making a change to a game mechanic will always confuse users who don't pay attention to patch notes or understand the difference, but the fixed speed system is far better for new players and far more convenient for everyone, so I don't understand the point of making it non-default and accessible via an option menu item that few players are likely to even know about.
This will allow you to use the same scroll speed for a 100BPM song and a 200BPM song, and have the notes travel at the same speed.But this doesn't seem to be the case in my practice, as I can set a 100 BPM song to a speed that I like, but then when I go to play a song at 200 BPM, the notes shoot down the page at lightning speed so I cannot see them XD
So the best update that mania has ever recieved got overrided because of negative feedback, which would be overwhelmed by positive feedback if whole mania community would discuss about this. Nice.hue, i was waiting for this update soo damn bad, and *poof*
