Dunno what to make of it. While GSX has always generated a few stutters during pushback now it's become awful and I haven't a clue why. Both MSFS 2020 and 2024 are tuned to perfection running super smooth so this really stands out. Of note it doesn't matter if I lock the rate to 30FPS, or my default 55FPS, or 60FPS, or wide open, it's no different.
Might it be I have a compromised copy of Simconnect or something along those lines if that's possible? All drivers, AMD chipset, NV GPU etc are up to date. Because GSX gets updates so frequently I run the updater every day prior to launching the sim.
