Vector V1 30 _best_: Fsx Orbx Ftx Global
You must run this you add a new third-party airport.
Let’s be honest: FSX is old, and Vector adds thousands of new vector objects. On a mid-range system (e.g., i5-3570K, GTX 1060, 16GB RAM), I saw a 5–10 FPS drop in dense urban areas like New York or London. But using the Vector Configurator to disable “secondary roads” and “railways” brought most of those frames back while keeping major roads and water features intact. For high-end systems, it runs smoothly with everything enabled. FSX ORBX FTX Global Vector V1 30
