So low to the ground the simulator work fine. On longer flights however, I get missing scenery tiles. This usually happens after about 20-30 minutes into the flight, when all of the sudden there is huge blue squares or triangles. If I hit reload the scenery it work for a few minutes, but the problem with that is that it loads the tiles in very low resolution, and when you go to land the scenery is pretty much unusable (extremely blurry). There does not seem to be anything special in the log. I have all of the scenery installed. What could be the problem here?
