actually, before i remove this thread, i'd like to make a few observations about this effect -
tbh, after seeing it a few times, i'm not that happy with it.
i've seen on several occasions when it kicks in while the aircraft is only doing about 650-700km/h.
also, it seems to happen way too much for my personal taste.
i'm actually going to quickly ask if there's an easy way to remove this effect, as these anomalies happen way too often, and it kinda kills the immersion factor for me, having planes constantly kicking in and out of this 'boom', while still flying at relatively sub-sonic speeds.
or if it was made to only happen on rare ocassions, i think it'd be better.
these are just my personal observations, i'm sure most guys are happy with it.
