Best Settings?

[SubaruPoptart]

For a long time now I've been playing with 40 FPS and some sort of rate. I haven't played in a while so I SWEAR the rate was something different back then, but now it just makes the song fast and like night-core and I don't really like it. XD

However I used to be able to AAA songs with ease, that doesn't seem to be the case anymore, mainly because I haven't played in a while, but it feels like something's different about my settings than it was the last time I came on.
I doubt anything's changed, however the fact it doesn't feel right unsettles me.

I'd like to play around with some new settings if possible. Maybe the best suited for you might work for me, too. Could anyone suggest some settings for me to experiment with?

EDIT: I seem to be getting goods at the exact same spot in several different songs, songs and spots I've been consistent on for MONTHS.
