AptX LL indeed has ~30ms of latency at the cost of bitrate, but last I checked it’s not supported by Windows out of the box. It’s also been generally dropped in favor of the higher latency AptX Adaptive due to requiring a dedicated wireless antenna. The default experience of Bluetooth is still >200ms of latency. Also 30ms is 4.2 frames at 140Hz.
I had an error in my calculations, read comments below for correct math

1000 (milliseconds in a second)/140(hz) = ~7.14ms per hz
Not sure how you got 30ms being twice as fast as what a 140hz monitor can display.
