NZFF

A new freeware app to reduce stutters etc in MSFS2020 (It is being worked on for 2024). Similar to AutoFPS but AI powered and is set and forget.
I've yet to try it out but it may be worth a look.
Available at Flightsim.to

Link: AeroTuneMFS

Had a go with this one.
I think only REX Atmos also wants you to manually enter a character string longer than my keyboard, but at the 3rd try I managed



It does seem to take out some previously noted stutters at Nelson.
But sadly it cannot co-exist with FlightControlReplay for MSFS which - still - is the only way to replay stuff in MSFS.
