Twenty-five million elevation points are modelled in 20 major cities, complete with railroad tracks, roads, rivers, mountains and smaller communities. Cross-country flights will be possible hopping amoung over 2,500 fully modelled airports. Airports and flight training will support the full gamut of flight sound effects, including Air Traffic Control radio messages, pilot to pilot communications, flight instructor suggestions and lessons, and engine noise. 356 square pixels make the terrain look quite good from 3,000 feet up. Planes are modeled with 500 polygons which makes them look nice.
Animation is said to be slick for even low level Pentium computers.
The lack of 3D acceleration hurts the illusion at lower than 3,000 feet altitudes. Frame rates are in the 13-19 range with Pentiums. Texture loading causes long pauses in the action. Your copilot helps keep you on course as well.
