With the version 1.6.2 drivers and later, you can set your latency alot lower than most drivers with better results, depending on your computer’s specs.
I usually record at 512 samples (I think about 22ms latency) and have output safely at 128 samples (7-8ms) when I’m doing listening or monitoring. The same driver updates were released for the UR’s and I heard some with superior systems getting down to 64 samples (no latency) without any errors in their recordings.
