Something's wrong with your setup. Typical latency for opus is only ~20ms and you can get it lower than that by changing an encoder setting. FLAC is usually more than that, but it should be negligible regardless. Maybe you are trying to decode Opus on an extremely low power device?

Whenever I went for low latency, I noticed 2 things: 1. Actual latency was not what I set in the encoder because of frame sizes, chunk sizes, tcp Windows, decided buffering 2. Forcing super low latency caused drop-outs, which is worse for music than delays.

Overall I just found flac to be rock solid and lower latency without much tweak
