Given that the aircrafts are "streamed in" to the msfs 2024 client is the flight model configuration files accessable, (eg Flight model .cfg) for tweaking? These were available locally in the aircraft folder with 2020.
For FG Tearing should stop if you activate VSync in NVidia Control panel and make sure VSync is off in the sim. This works on my system as I have a 13900K RTX 4090 4K monitor 60Hz with frames capped in NVCP at 60.
