During the FSX and P3D era, sceneries from developers like Aerosoft and FSDG set high standards for realism, detail, and performance. FSDG, in particular, became synonymous with extremely detailed and authentic airport sceneries, often featuring hand-crafted 3D models, detailed ground textures, and dynamic lighting. Their work on airports around the world, especially in Europe, raised the bar for what simmers could expect from their virtual airports.
