Noticeable Audio sync lag

I have just begun using Beta 20 (downloaded and installed 14th May 25) and I have become aware of a pronounced audio/video sync issue where the audio often gets maybe 15 or 30 frames behind the video. This wasn't at all common on 19.

Nothing has changed in the system other than the latest nvidea studio driver installed and DR20.

I can't see any other mention of this elsewhere, so maybe it's just me?

I haven't seen this widely reported. Post up some details...
