Nothing in the GSX code, or the whole FSDT software, requires, reads or write the status of the Flying tips setting, which is controlled by the QUICKTIPS=x ( 0 or 1 ) setting in the Prepar3d.cfg file.
Of course, I tested it, and if I disabled all tips from the settings menu, and I call GSX, it stays disabled. And it also stays disabled if I exit the sim, then enter it again, and call GSX again. No change to the settings, which is to be expected, since nothing in GSX relates to it.
The only option that matters for GSX to work, is the "Message Text", which is NOT the Flying tips, and it's controlled by the ShowMessageText setting instead. But we don't set this automatically either, we only have a warning if it has been disabled, since it's required by GSX to operate correctly.
