Detailed Description

A wrapper around NVidia GSync support (when using X11 and a Display Port connection).

If libXNVCtrl support is available through the MythNVControl class, then we can check for GSync capabilities and state. Note however that any changes requested to the GSync state will have no effect while the current GUI is running; so if we want to enable/disable GSync it must be done before we create the main window (and we can revert that state on exit).

◆ ForceGSync()

void MythGSync::ForceGSync ( bool Enable )

static

Enable or disable GSync before the main window is created.

If the state has been changed, s_gsyncResetOnExit will be set to true and s_gsyncDefaultValue will be set to the default/desktop value so that the MythDisplay instance can reset GSync on exit.
