1. Load up the new update.
2. When it's raining or windy outside, go in and between indoors and outdoors.
3. Listen to the audio and transitions, (there's no soft fade in audio to each, just rough silence or rough transition to loud rain/wind)

+
If it's raining, windy, or normal weather outside

1. Go indoors
2. Check if you can hear any ambient sounds of rain or wind what so ever (rain hitting the roof quietly, wind quietly blowing outside )

(Player Audio wise) I'm not sure about player audio, so it may be okay, but it's highly possible it can be bugged too
test footstep sounds w/ another player if there are any issues.
test between or in buildings, different distances, different types of terrain

^ same for reloading, eating, drinking, and gunshot audio

Also, Clouds on medium settings.
But Blue sky, with some clouds and still raining?
and on High cloud settings, it only becomes fully cloudy.
as shown in the second clip w/ hunting stand
+
Sunlight flare even though it's cloudy and raining.
