A question about Nvidia Optimus and HD Video.

[kritom]

Hello,

This is my laptop: http://www.pcspecialist.co.uk/computers-for-next-day-delivery/127/

I have recently purchased a laptop with Nvidia Optimus, and while watching HD videos I noticed that my CPU %usage would go up to about 50%.

I also play a game called Runescape (2007 version) which also runs on the CPU and takes up around 40% ( 2 Clients loaded up)

So that is nearly all my CPU being used while my graphics card is doing nothing.

l had a quick look online and it appears that for HD Video my graphics card should kick in, but it doesn't and I can't seem to force Chrome/Firefox or IE to use the card as the options are greyed out and not click-able (unlike in the Nvidia tutorial video.)

The graphics card does kick in for games on steam, so it is working fine for that.

I also have my Graphics card as the preferred graphics processor.

Thanks for any tips you could give me,

Kris.


Edit#1 It appears to have started working for a twitch stream, lets see if it keeps working.

On my Optimus IV there is a VGA button at the top right of the keyboard, I'm guessing the Optimus V has that too? It's very important that this button is orange in colour; that switches Optimus mode on where the GPU will switch in when needed. If the switch is green then it's in the lower power mode where the GPU is not used. You might also find this thread useful?
