// The ThreadPool has something called a "GateThread" which terminates itself after some inactivity.
|
||||
// However, it immediately starts up again, since the rules regarding when to terminate and when to start differ.
|
||||
// This creates a new thread every second or so.
|
||||
// The main problem with this is that the thread snapshot can take 70ms, is on the OpenGL thread and will delay rendering any graphics.
|
||||
// This is a little over budget on a frame time of 16ms, so creates a large stutter.
|
||||
// The solution is to keep the ThreadPool active so that it never has a reason to terminate the GateThread.
