Flash and silverlight cause high cpu usage when watching movies online - high temperatures, loads of fan noise, high power consumption...
But on a newly created test account everything works fine (and it used to work fine on my own user account.)
So yes, I can use the new account to watch iplayer and LoveFilm and everything, but...
how do I find out what is going on?
Clearly there is something in the user files that is messing things up, but how should I go about finding what?
I can open the user library and clear the caches, but other than that I can't see anything that pops out as something to investigate.
Any ideas anyone?
osx 10.8.2, all stuff up to date. Happens on all browsers (though you could probably find some obscure ones I haven't!)
I've tried changing varioius application settings (hardware accelleration and not etc.)
