I have a problem where when I climb above about 20 000 feet, I get missing tiles and I see huge blue triangles/squares. This happens at every location I tested at. I have an old computer (LGA 775) but the frame rates are ok at low settings. Does anyone know why this could be happening? When I hit reload scenery, the scenery shows up, but is at a very low resolution and when I drop to land, the scenery is so blurry that it's unusable without constantly reloading it. I have all of the scenery installed, nothing special going on in the log as far as I can tell.
