Flight Dynamics Settings

I’ve tried all the different FD settings and I haven’t noticed a difference.

What should I be looking for?

Are you talking about legacy and modern flight modes?

If so, only use Modern.
Search forum for more info, it’s been discussed exhaustively.

Yes Im talking about those settings…and yes it has been discussed so exhaustively thats I cant find the part where my specific question was answered!

I haven’t noticed any difference between modern and legacy, what should I be looking for?

My understanding is that the Legacy mode is there to specifically support the use of aircraft that have been ported from FSX. Unless you are using such aircraft there is no point or sense in using the legacy setting. Any aircraft that has been developed for MSFS should have been modelled to use the modern setting.
