decrease quantum for osu!lazer when running with linux and pipewire?

[Fxzzi]

Hi all, I've attempted what I could to decrease latency for my system and for osu!lazer specifically, I followed this guide:

https://www.reddit.com/r/linux_gaming/comments/1gao420/low_latency_guide_for_linux_using_pipewire/

After setting everything up, it seems osu!lazer (alsa) is still limited to a quantum of 441, whereas my min and max are 64 and 128 respectively. How could I get osu! to respect my max quantum and therefore lower my audio latency further?

Lazer currently has a hardcoded period size ("quantum") of 10ms at a 44100Hz output sample rate. You can force the period/buffer lower with environment variables when running lazer:

PIPEWIRE_LATENCY=64/44100
PIPEWIRE_ALSA='{ alsa.format=S32_LE alsa.channels=2 alsa.buffer-bytes=512 alsa.period-bytes=256 }'

This question has already been asked before, but it seems the original thread got taken down for some reason.

We don't "take down" threads, so users that posted the previous discussions likely either "closed" their discussion threads which is a thing you can do now and which shadow-realms the discussions out of search results, or they deleted their accounts, which also does that but harder.

Thanks! using just the top env var seems to work fine and pw-top shows 64 perfectly. However using the second one as well causes my osu to be slowed down and crackly.
