Massive CPU usage on auto rotate
Posted: Wed Jun 24, 2009 12:40 pm
Hi,
We recently converted a whole batch of QTVR movies to Flash, and have integrated these on our pages in place of the Quicktime versions.
The Flash VR's have the auto-rotate feature, but we have noticed incredibly high CPU usage on users machines when viewing the pages.
Checked the samples on the Garden Gnome site and can see the same high CPU loads when the panorama is rotated - example this page:
http://gardengnomesoftware.com/samples/ ... flashtour/ CPU usage is about 7% when at rest, but when the pano is rotated this increases to 140+
Noticed this initially on my laptop - if a browser window is left open with a Flash pano on display then the laptop starts cooking and all the fans kick in.
Any tips? obviously we could remove the auto-rotate from our movies, but this is hardly the best fix- we DO want viewers to be immediatley aware that they are not just looking at a still image.
Example page of ours - check your CPU usage when viewing the page (Mac users - just go to Utilities/ Actvity monitor) http://www.vrscarborough.co.uk/virtual- ... useum.html
I am looking at this page on an 8 core 3.2ghz and CPU usage is showing at 118%
Any ideas?
Thanks
