See this thread: Poll: Nvidia 497.09 Experience [Update: 497.29 drivers with fixes available now]
Hello everyone,
We are carefully monitoring reports from our players that the latest Nvidia Geforce driver (497.09) may be causing issues with Microsoft Flight Simulator, including, but not necessarily limited to, crashing to desktop (CTD) and blue patches where ground terrain textures should appear. Please vote in this poll so we can better understand how widespread this issue is and if it is affecting everyone who has upgraded to the 497.09 driver or only a subset of players.
Please choose the appropriate option for your version of Windows (10 or 11) and which DirectX version you are using (11 or 12).
Thanks,
MSFS Team
