Hello, first I would say that dynamic objects are very cool. But I can testify that it eats a lot of memory and it leaks it. I am under Win2k, compile with MSVC a debug version. On startup it takes 586 Mb (read Mega) but stay still while sitting on the runway (LFLK is surrounded by forest of SomeSort material ). Then I take off and engage AP, flying A4. It then leaks 80Mb from time to time, saturating the 1Gb of ram and begins to take swap memory. I stop it before all my hardisk eaten by the Windows PageFile. CPU is 100% of my Athlon XP1800+ before beginning swaping.
By comparision, startup consumes 220Mb without dynamic objects and no more memory is reclaimed after. CPU is about 50-60%.
