I watched your track. The text, as well as the actual aircraft "dot", is visible all the time; from the starting distance (about 1.20 or so), down to .80, where you slow down, and then up to around 5.30, where the text is no longer readable on my resolution - but I estimate it stays there up to 5.60 or so.
Then, I watched the track again, this time with MeshShowLod=1. This yielded the exact same result; the plane as well as the text remained visible all the time. Exactly the same, with no newly introduced stutters or so.
Meanwhile, on ATAG, I searched in vain for a 14-plane Ju88 formation, as advertised by "Chain Home" - nothing, except for a few flak puffs.
Then, I got shot down over France in the usual manner - Bang, Bang, critical dmg, Pilot dead - and after pressing Alt+F2, I was able to see the corresponding Me109 for the first time...
This must've been a happy time for the Me - Pilot
So I'm still at a loss and still begging for help!
P.S.: That other file, "confs.ini" in the Documents/1C.../il-2 sturmovik.../ folder has an option, under [core], called "LinearObjectManager(=1)". Could this be relevant in any way?
