Of course I can’t hear a 7ms audio delay difference 
I just wanted to test a perfectly adjusted setting for all refresh rates 
I already tried yesterday to combine 23.976, 24 and 25 Hz settings in one stance to no avail. I even tried to reverse the stances, like 1080 after 2160 in case there was a parsing bug, again with no luck. As I said, I spent more than 2 H yesterday trying everything.
For now, I’m back to 20241129 which works perfectly well with one setting but obviously, this is not a future proof solution.
I’ll keep the 20241206 on my test USB stick in case a new nightly release brings something to the table.
