Each person’s computer is different, I don’t push everything to the limit on mine.
All my settings are default by MSFS did some tweaks but nothing major.
With the A320neo I never get less then 20fps flying online with traffic and real ATC controllers, and outside of dense populated area is a constant 30 fps Most of my setting are on High, some Ultra and I disable Ai traffic I don’t care about real world traffic only traffic flying online on IVAO network.
