Further evenings experimenting and troubleshooting, I’m now certain, what in my case was causing the stutters onfinal approach to touchdown. VRAM usage spikes up short before landing. While I still think, there is a lot to fix in the sim, there’s workaround to make the sim usable at this point of development. Turning down the texture resolution to high or even to medium at performance intensive airports. Visual degradation was not really visible in the iniBuilds 3xx, however in the Fenix. But you’ll really have to take a closer look, in my opinion. For reference, I run an RTX4070 Super with 12GB + Ryzen 5800X3D + 32GB Ram + 250-300Mbit/s internet connection (fiber opt.). I don’t expect my rig to run Ultra in 4K, just decent enough at fairly high settings in 1440p to justify the sim upgrade.
One more thing, another FPS-Killer is the in sim real-time traffic.Hopefully, FSTL will be compatible with MSFS2024 soon 
. Hope, this helps.
