Re: FLASH: site check/fps advice

[sharon almeida]

Hi


Thanks to both you and Tom for your advice!


I am testing on a 300 MHz G3 (plain old beige) with 320 MB RAM, 6 MB video RAM. The video card that came with it from Apple, but it has a

built-in 64-bit graphics and multimedia accelerator chip. 


The part where the deep blue line expands to fill the back drop seems jumpy to me. But other Flash animations I've done seem to be smoother

(www.provenbrands.com). I've been looking over optimizing tips in every book that I own and haven't found any new ideas. 


Could it be the large (960 x 360 pixels) movie size?


Thanks again,

sharon
