Question

Slow Speed

I am using a Dell Precision dual core laptop. It has 2 gigs of ram and a 200 gig harddrive. When playing back a presentation Captivate 3 runs very slow. When looking at the task manager, Captivate is using 50% of processing power but no more. It looks like Captivate only uses one core and maxes it out thus the slow speed. Was captivate only meant to be a single core application? According to tech support Captivate 3 should fly on our system. We've tried the trouble shooting tips listed on document kb402464 but to no avail.

Thanks

    The only rule of thumb I know of when dealing with slide dimensions is "as small as possible"... use the smallest size you possibly can and performance should improve and your users will also see a drastic reduction in the download time needed to view each presentation.

    If you use your minimum size and performance still isn't where you'd like, try publishing your project with a combination of borders turned off, and also using one of the Captivate 1 BMP-based skins (should be the last item on the Skins menu).

    If my experience is any indication, your CPU usage during playback should go down substantially with each change. It's then up to you which trade offs you want to make to reach your performance goal.

    Our users access materials in a Citrix environment, so we publish with both borders off and a BMP-based skin. Borders off means the playbar overlays the bottom of our content, but we're willing to live with that to maximize performance.

    Hi gneb and welcome to our community

    As to whether Captivate has been designed to only use a single core, well, I'll have to defer to someone on the Captivate development team to answer that. Unfortunately, they are all busy working with the application and not hanging around here answering questions.

    To me, the larger question here is to ask about your project. How large is it in dimensions? (Number of pixels recorded) How many slides do you have? How did you record it? (Full Motion?)

    Perhaps the answer to your issue lies in what we see of the answers to these questions.

    Don't you just love it when you ask a question and receive more questions in response?

    Cheers... Rick

    Hi,

    The projects I work on typically are about 120 slides and about 200 megs. The project are simple slide presentations with voice over. Thanks for your help.

    Hi there

    At 120 slides, you are about double what we normally suggest as a *rule of thumb* guideline for what to consider as an upper limit. You might wish to save as a copy, lop off the first 60 from one and the second 60 from the other, then configure the first to automatically open the second when it completes.

    Just a thought... Rick
