High CPU usage in Flash/firefox fix (partial)

first don't keep your hopes high.
second it works for me
third I have nvidia 7400 Go
fourth it supposedly works better for intel cards.

method:
create /etc/adobe
sudo mkdir /etc/adobe
create file
mms.cfg
with this content:
OverrideGPUValidation = 1

move file to /etc/adobe

that is all
in my case this decreased CPU usage from ~70% to 45%. Not bad though still far cry from windows.

hope this will help

Maybe it is because my intel card doesn't need it (945GME, without compositing).
Will try nvidia soon.

Re: High CPU usage in Flash/firefox fix (partial)

Thanks for the tip, videos are now watchable on my laptop in firefox, before the sound would glitch out and video would be choppy.  Had to use midori or opera.    Ironically, midori videos seem to be slightly more choppy.  This is the only tip I have ever seen despite google searches for this exact problem.  I have a 1.5ghz celeron with 768mb ram.  I am using ati driver for x200m card in my laptop.  My cpu is high but performance is better.  Thanks again!
