4.Stick stirring limitations.
If anyone knows of other things which forcefully limit the gameplay, please respond below. These were the only things I could think of at the moment.
What limitations should those be? Remember that our controllers that we use really don't simulate the feel and forces that real flight controls experience, and would not be able to perform or even survive the forces caused by the stick stirring that is possible with our computer controllers.
The message that you get for stick stirring is also rather helpful, as it can be the first "alert" that either your controllers are starting to go faulty or your controller settings may need adjusting.
Let me see if I can explain this...the joystick signal is broken down in numbers from 1-255 for both axis and is read sequentially back and forth, 1...2...3...4, etc. The signals are read at a certain speed (not set by the game, believe its DirectInput, part of DirectX), and if that speed is exceeded, things get skipped, like 1...2...3...4...28...etc,. That skip is either caused by the controllers being too fast or there is something wrong with the controller, most likely a potentiometer with a dead spot. It's actually a legacy of the old analog days when there were speed adjustable dedicated game cards that you could dial in the speed to avoid those spikes. Even though now everything is USB, nothing has changed how it works.
To address the last part of your post, no, the stick stirring limitations don't forcefully limit game play at all. It's not allowing you to move your stick in such a way that would be impossible in real life to do, if that's not the reason you're getting the message, then it's most likely a hardware issue causing you to get the stick stirring message.
