[MSFS 2024] Pilatus PC-6 Performance Issue

I’m having severe performance issues with this particular aircraft, like no other. Even heavy airliners perform perfectly well on my system. But this one is truly unflyable. VRAM gets severely hammered as soon as I initiate a flight and enter the cockpit. Anyone else having issues with the PC-6?

Today i tried to fly on Pilatus pc-6 first time in msfs2024 and i have exacly the same issue. It shows messages that my gpu memory is not enough. I have rtx4080super. In msfs2020 everything worked perfectly.
