I think that’s a common thing and how the MSFS works. The textures look blurry because the game engine still thinks that you are on the runway 31 and because of that it lowers the resolution of textures far away to increase frames. If you change to drone cam and zoom out a bit and then zoom in again, they should load correctly. I don’t think there is anything to be done about that, it’s just how the game works.
