Pipewire is the replacement for JACK and PulseAudio, Pipewire allows low latency compared to any pulseaudio tweaks

Here is a short list of what you should do to get the lowest latency in Osu!

Higher audio rate equals less latency always, unless you increase your quantum
to calculate node latency for your audio device take the quantum size divided by your audio rate
so 64/96000 = 0.00066666666 * 1000 = 0.6ms this is 0.6ms node latency

To check client latency use pw-top, take the quantum size and the audio rate of the client then use quantum / audio rate * 1000
to get overall latency for the client
