Hello everyone,
Recently I had this problem (or noticed it): when in cruise, the terrain textures are not loaded, exceeding more than 40 nautical miles... This is: the textures are loaded in a radius of 40 nautical miles, but outside that radius, nothing is loaded... It's like it is desert. The same for water: water textures are only loaded in that radius. Outside the radius, it appears a flat blue surface.
Can't upload the pictures, sorry for that.
Waiting your thoughts on this, cheers
