The frame rates are too low when using new dynamic objects. How can I improve them?
Most FSFS aircraft are very detailed. They consist of a large number (sometimes over 100) polygons. Each polygon takes some time to draw, therefore a large number of them has a significant impact on the frame rate, even if they appear very small on the screen. You should try to find less detailed aircraft. If you are an aircraft designer yourself, try simplifying your aircraft by reducing the total number of polygons. This procedure should be familiar to many people who struggled to fit FSFS aircraft into the 16K limit for static object in the days of FS5.1.
