I think I got confused by these two notions… according to the flex documentation (even though I’m not using flex, bur I couldn’t find any info anywhere else), render is the when flash draws the stuff, and pre-render is when flash configures the clip before placing it on stage?
In my app there’s 300 clips constantly moving on the stage. When I check with the profiler it indicates that pre-render is using lots of resource. However when I change the clips’ visibility to false there’s almost no pre-rendering. Shouldn’t that be rendering’s job?
