If you are finding iPlayer or Youtube videos are using excessive amounts of CPU, it might be worth trying this fix

Simply create a folder in /etc called adobe (assuming it doesn’t already exist)


sudo mkdir /etc/adobe

now create a file called mms.cfg with this single line in it:


OverrideGPUValidation=true


sudo gedit /etc/adobe/mms.cfg

Now save it and restart firefox and you should hopefully find your flash video performance is dramatically improved. I got a 30% reduction.

It says intel graphics cards only, but its worth a try if you are running another or you are not sure.
