Yeah, thats just a problem with FSX. Ive tried (with bad results) to get a different acting vapor (hiAoA, hiHUM, HI-G LARGE vapor), but even tho I coded it with delays, the effect was unsynched and looked really bad. The hi G would come on before the med G vapor and theyd both intermix even tho they were coded (thru .XML gauge) to come on at different times. So I gave up and just settled for the med G vapor. As my tag line used to say, "the best of what's left". Sorry, I tried, cause I know exactly what you are wanting, just didnt work.

That would take Virtuali making some big changes. So NO it probly wont happen.
