Hi Darren, The line you pointed out on the guacamole source is the framerate at which the videos produced by the guacenc video encoder utility play back. It has nothing to do with live usage of guacamole in the web browser as these videos are encoded after a live session has already completed and ehe guacenc utility has been executed against any recorded guacamole protocol files that guacd produced.
As for why you're seeing latency connecting to VNC sessions on macOS installs, I can't comment directly, but based on your description, my guess is that your instinct is correct and that Apple's VNC may be the culprit. Hope that helps, Sean On Mon, Oct 7, 2019 at 3:20 PM Darren Wise <[email protected]> wrote: > Hey folks, > > I'll try to keep this short..
