in your performance test in Firefox, all seems same for me, little bit blur has slower
but CPU usage on blur: 38-40 % on convo: 34 - 38% my previous tests was in Flash IDE On 1/31/06, Cédric Muller <[EMAIL PROTECTED]> wrote: > Actually, I don't have time to write a small 'performance' reporter .... > but I did upload the files so most of us can see them live ... > > WHAT IS IT ??? pure crazyness .... > > http://www.benga.li/performance/ > > Cedric > > > > > my mails seem to fall before getting to the list... > > I am on OS X 10.4.4 using Flash 8 on a G5 dualcore 2*2ghz > > > > ouch!!!! > > WHAT IS THAT ????? > > > > we are in a bad shape ;) > > and macromedia is the only one to shed some light on 'hardware > > acceleration' > > is it ?? > > > > cedric > > > >> uff, Cedric, i got opposite results > >> > >> blurFilter=shaky and unstable > >> convultionFilter=svery smooth > >> > >> can anybody tell me why? > >> > >> > >> > >> On 1/31/06, Cédric Muller <[EMAIL PROTECTED]> wrote: > >>> ??????? > >>> blurFilter=very smooth > >>> convultionFilter=shaky and unstable > >>> > >>> > >>> > >>>> much better with Convolution filter :) > >>>> > >>>> On 1/31/06, Mike Mountain <[EMAIL PROTECTED]> wrote: > >>>>> OK you'll need a movie 768x768 - copy this code on to frame 1 etc. > >>>>> > >>>>> with blur filter: > >>>>> > >>>>> [/as] > >>>>> import flash.filters.*;
