Projection Quality	Flight Explorer supports four quality levels with which to display background images. You can customize this quality level to suit your preference of screen draw speed versus image quality. A lower quality display setting will draw images on the screen faster when zooming and panning your view, however the image will sacrifice fine detail. A higher quality display setting will draw somewhat slower on the screen, but will enhance the image to produce finer details. Low (fastest) Good (best speed / quality tradeoff) Better Best (slowest) Note Speed and quality levels are largely dependant on the original image quality, image and compression types, and computer hardware that is running Flight Explorer. Anomalies and performance degradation may be present due to these factors.
