I recently installed Windows 8.1 professional 64bit (UEFI) on my T420s.
I tried the official Drivers from Lenovo, and also the latest Drivers from NVIDIA.
I also set Display in BIOS to "Discrete" and "Optimus", but nothing worked.
I use an external Monitor and the integrated Laptop Display and I am not able to play 1080p Youtube Videos in a normal framerate. They are very choppy and the sound also..
The fan is working nearly fulltime in full speed..
Also the integrated Laptop Display sometimes flickers.
The Laptop just feels sooooo slow and that's a shame for such a decent device.. =(
Anyone has a hint for me? Do you need more data?
Kind regards, Tim

This should not happen in Chrome, have you checked updating the chrome and the Adobe flash player with latest version?

Chrome and also Flash Player are up to date.
(THough the youtube player is html5)
I also tried several things like disabling hardware acceleration in chrome and other flag stuff.
IE is fine, but who likes IE?

I don't have this option with the constellation now. (Running on discrete graphics.)
Also I'm running Chrome stable. I will switch to Optimus and then see, if I have the option with right click.
