Even the low impact Asobo GA models will have more impact than the current generic AI models. When combined with whichever airliner AI package is also in use, the FPS impact could be severe on some PC’s.
If Asobo choose to add more generic models themselves, they will be incorporated into Offline GA Traffic. I’m currently working on a newer and simpler fix for eliminating the default AI of all types, which hopefully will be a permanent fix - it will work until the user removes it, not a future Sim Update.
By the way, has anyone tried using the MSFS Offline traffic mode since SU11? The low-flying airliners are gone, airliners spawn at sensible altitudes and they fly at different altitudes to the user’s plane. AI Ground and AI Flow work with offline traffic as well. I’ve even seen contrails!
