I've gotten some weird latency issues ever since updating from 0.5.3 to 0.6.4
Not only has my measured audio latency increased (24ms or something like that to 40ms), no matter what number I set the frequency to, the notes still hit the strikeline before they should, so I have to hit buttons early. Setting things to +100 or -100 or more makes it clear that the offset doesn't shift the notes as it should, it just makes the game act weird even if you DO hit it on beat, including missing notes when you're right on top of them.
I'm going to open an issue on Github, but I'm wondering if anyone else has experienced similar issues. I personally can't play rhythm games properly unless the audio sync is perfect.
