LSM Published SL3 Presentation Like Molasses

Jun 03, 2020

I have published a new SL3 presentation to our LMS and when employees began taking the course, some employees  had no problems viewing the presentation--the narration, animations, avatars were all in sync and played without problem.  However, for many others, the presentation is erratic and slower than molasses--narration would start and then have long pauses; narration finishes and the remainder of the slide information may take as long as 10 minutes to finish; simple animated graphics or text boxes could take up to 2 minutes to display;  no synced animations; and the audio levels for some of the slides drops so low that even when turning up computer/speaker/headphone volume its almost imperceptible.  

It appears to be a buffering issue and perhaps a computer configuration issue.  We looked at computers that played the presentation correctly and those that didn't.  All are working on Windows 10 machines with different RAM, delivery is thru GeoMetrix Data Systems' GeoTalent LMS from a dedicated server.   

RAM in machines that played the presentation correctly ranged from 4GB to 32GB.  RAM in machines that we looked at that weren't playing correctly ranged from 8GB to 16GB.  Our IT group is checking the server and connections to see what may be creating irregularities.

I am wondering if anyone has had similar problems.  And if there are things that could be done in the design of the course--no animations, no avatars, using .MP3 vice .WAV audio files, and converting .MP4 video clips to something else.  OR in the publishing of the presentation by not including the search bar (play and pause) and minimizing navigation options.  

Any ideas from the Articulate Team or experienced users will be appreciated.  Love to hear back on this...

Hi Layne,

Thanks for taking the time to share such a thorough description. Happy to help and I'm hearing two questions:

  1. Why is the presentation erratic and slow for some?
  2. What can be done in the course to help the affected learners?

For the first question, I believe it's a trifecta: low-bandwidth, server, and connection. Keep us posted on what your IT team finds!

You could also ask the affected folks to check their connection speed using free tools like Speedtest or

A few thoughts for the second question:
