h.265 and VP9 hardware decode on Haswell

Is this only when using the IGP? Or can it be taken advantage off with a discrete video card using any player with ffdshow?

I think you have to do the 'quicksync hack' to enable this if you are using a dGPU. Don't quote me on that, but I believe the dGPU has to be enabled as driving a display to work.

I noticed the same for a different set of newly released drivers for my Ivy Bridge laptop. You can still install it using the 'Have Disk' way mentioned in the readme. I ended up getting a permissions error on some files, but on reboot all is well. Therefore, I recommend uninstalling the previous version, then doing the 'Have Disk' method.
 
CPU usage on the 4K Elysium trailer on my 4770 is around 15-20% with HD 4600. Old driver was around 25%. It isn't exactly "hardware" decode either, MFX won't support that until Skylake.
 
Update.

Intel's more recent driver(03/06/2015) doesn't bring that much of an improvement. CPU load on youtube chrome on vp9 is ridiculously high compared to youtube IE on avc.
Even worse, those new and good looking 60fps VP9 videos load the hell out of my modern haswell 4770's cores.

Current chrome's VP9 GPU hardware assisted decode is a joke compared with IE.
I'm wondering if microsoft will stay with this or will make the switch to VP9 starting with Project Spartan.
I enjoy chrome a lot, but it needs to become highly efficient also, not only highly functional.

Yep, HP. Probably a registry setting somewhere that prevents the install. When my HP desktop had an ATI video card in it there was a registry setting that disabled Overdrive.

It does that on most laptops, no matter the manufacturer.

Have you tried uninstalling current driver and running installer again? It works for me on both Asus and Toshiba.

PS: NVM, I missed previous advice from razel.
