I don't know what it is .. grrrrrrrrrrrrrr
I was thinking that some of the ships next to the coast were sinking incorrectly. There would be a never ending message in the console that would say shipsinkcompute NAM over and over and over and it seems when that started there were stutters etc. So I've gotten rid of all those (at least for the 4 hours of testing I did). Maybe spawning too many planes at once causes the error? Either way it appears that it's 2 or 3 groups that always do this while the rest all go to target. Maybe I'll make even more sub missions that have smaller amounts of planes? Well at least without the ship compute errors running all the time, it seems very very smooth now.
Or maybe we'll get a patch lol that fixes this crap!
@Snafu - I don't think there's anything wrong with the standard scripts (the one's for the game) but I wanted to do it the old fashioned way (process of elimination) to make sure that was the case.
I'm loading up 45 sub missions through .cmd files right now. Basically one .cmd file opens a mission and with the timeout command waits to open another .cmd file set to open another mission.
