/* Device detection can be extremely costly performance-wise, in some cases.
|
||||
In particular, if no devices are connected, calls to detect a single device,
|
||||
via either XInputGetState() or XInputGetCapabilities(), can take upwards of
|
||||
20 ms on a 1st generation Surface RT, more if devices are detected across
|
||||
all of of XInput's four device slots. WinRT and XInput do not appear to
|
||||
have callback-based APIs to notify an app when a device is connected, at
|
||||
least as of Windows 8.1. The synchronous XInput calls must be used.
|
||||
|
||||
Once a device is connected, calling XInputGetState() is a much less costly
|
||||
operation, with individual calls costing well under 1 ms, and often under
|
||||
0.1 ms [on a 1st gen Surface RT].
|
||||
|
||||
With XInput's performance limitations in mind, a separate device-detection
|
||||
thread will be utilized (by SDL) to try to move costly XInput calls off the
|
||||
main thread. Polling of active devices still, however, occurs on the main
|

thread.
