I am profiling my game and for the first 15 minutes i am getting 60 fps. After that the fps drops to 45 -50 and after 5 minutes the fps drops to 30 and so on .
By using profiler everything seems OK except for
idle time , its the reason for low frame rate, Its high.
My Memory usage and object count are constant .
What exactly is
idle time and why is it increasing over time ?
