Odd behavior of GPU - Sandboxing or something else? (Computer Guru???)

[JoeSchmuckatelli]

Does YouTube have the ability to sandbox GPU time?

I ask this because I have been sitting here, no games running, merely watching a YouTube video, and suddenly my GPU spins up.  Fans going quite loud and dedicated GPU memory usage climbed to ~2gb.  (The abrupt spool up made me pull up Task Manager and see what was going on - there was a brief spike in "3D" to abt 21%)

My first guess is that something started sandboxing GPU time - but I don't subscribe to any folding ops or anything like that.

The whole event lasted about 2 minutes.  (weird)

 

Any ideas on what the event might have been?

some websites tend to make the gpu go wrrrrrrrrrrrrrrr. these also tend to be websites with a lot of ads on them. one of the reasons i run an adblocker. i dont mind ads but when they start running scripts in the background i have to question my own online security.

When entering the particular webpage type 'ctl+u' (Control Key plus 'U')

This should open the another tab, and fill it with the html code + any initial java script code - Save this 'text' page for analysis.

Java script is the scurge of the internet, and you'll probably find that java script is loading 'shaders' used for other purposes than the web.
