Hi, One question comes to mind immediately.... you mentioned that you "altered the app update rate appropriately". Was that modification of this line: appUpdateRate = 1.0 / 24.0; in main.cpp? If you set this to be 1/1000 what happens? Also, you mention removing a piece of debug code - could you be more specific? Is this a debug or release build?
