Description ejhndz91 2022-05-18 00:56:04 UTC

systemd recommends to turn off real time group scheduling in kernel config. My testing shows that enabling it causes rtkit to not be able to set processes to real time and causes audio crackling and latency spikes in some video games.

Reproducible: Always

This is really a decision the user needs to make; there are tradeoffs either way.
