Presentation mode - delay update of notes

[Martyn Wheeler]

Hi,

On old/slow hardware the presentation can become a bit laggy when using presentation mode.  I'm guessing that this may be caused by simultaneous updates of the presentation in the main window and notes window at the same time.  I was wondering if it would be possible to delay the update in the notes window until the main window has finished stepping on? Maybe someone else has looked at this already, my javascript skills are not yet fully honed so if someone can give a few pointers?

Thanks

Martyn

You may just want to disable the animation with:

transitionDuration: 0,

animation: {

transitionDuration: "0s",

transitionDelay: "0s"

}

Hi Tobias,

Thanks for the reply.  Is it possible to do this just for the presentation-screen.html file?  Below is the relevant part of my file at the moment. or do I have to put it in the main presentation file?

Cheers,

Martyn
