Lenovo Yoga 2 Pro Video Graphics driver

2013-12-26, 12:16 PM

I try to watch some 4k video and see that cpu load is very big and some of the frames skiped. i look at intel knowlege base, so it is known issue with 10.*.* drivers and they recomend to update to 15.*.*.*

link to driver https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23405

So i try to install it and get message that my sistem didn't test with it and i need to contact with manufacturer.

 

I have 2 questions:

1 when 15.*.*.* intel  graphics drivers will be availible for lenovo Yoga 2 pro?

2 What is the reason to not allow instal the generic drivers?

Still you can install it manually, download zip (instead of exe) file, decompress it and update the driver from Device Manager.

Bump: trying to update manually (just for the sake of having the latest driver) and it says I have the latest driver installed (which it is not, 15 vs 10 and a month newer). Any workarounds or do I just have to wait for Lenovo to possibly post a new one?

 

Edit: Solved! You just have to uninstall the previous driver. The latest intel 4400 driver is 3 months newer than the one lenovo offers.

 

Edit 2: CPU is reduced by 20% on 4k videos but the lag/frameskip persists. The current fix I use is just downloading the video (if it is on youtube) and playing through vlc. I usually prefer MPC + madVR but it simply is not smooth enough (even on bilinear only lowest settings).

 

Edit 3: Gained 10 fps or so in team fortress 2. Really playable now on 720p res + medium settings.

Intel has released a new graphics driver, version 3960.

 

It looks like the new driver has been vastly improved with better battery life, much better performance, fixed issues and new features. Sounds good!

 

From the Intel download page:

"This driver provides significant gaming performance for 4th Generation Intel® Core Processors with Intel HD, Iris™ and Iris™ Pro Graphics provides improvements while enhancing battery life through newer power conservation techniques such as CMAA* and Adaptive Rendering Control. Experience up to 30% improvement in performance in certain OpenCL workloads and up to 10% improvement certain games. The new and enhanced control panel offers additional media and display customization capabilities."

 

 

For those who have stock Lenovo graphics driver - in order to install the new driver from Intel website you have to first uninstall the current stock graphics driver from Lenovo. Just uninstall it from Control Panel, Programs and Features. After that, install the new one. Reboot might be required.

 

 

Note that "Panel self-refresh" option from Power options ("On battery" options, drop down when clicked on "Power" in top left corner) in Intel graphics control panel might cause ocassional screen blankings and shiftings.

Those glitches used to appear only when on battery and every few hours, more or less. But, that might have been fixed by Intel with this update, let's see.

Those blankings/shiftings are software driver issues, and  appear only when this option is enabled AND when on 3200x1800 resolution, and usually last only few seconds. If longer then closing the lid and opening it straight away fixes it.

Lenovo stock graphics driver has this option completely removed from Power options.

 

The reason for enabling Panel self refresh option is it offers much lower power consumptioon of the display at native 3200x1800 resolution. Expect around 1-1.5 hours better battery life with this option turned on.

 

If you really need more battery life then enabling this opton is worth ocassional screen banding/shifting.

Oh, and this never happens when playing video, so it won't interrupt your movie watching... :-)

Thanks for the great improvement in performance: both speed and battery!

 

Not only for the Y2P, but also for the Y2 13 ..

@splus - thanks a million - even though it was the wrong thread for your exchange of info on the graphics drivers at least now my high res display and window scalling is working great for the first time - I can even use photoshop on full resolution!!! Cheers.

 

- how about updating your drivers more often?


 

mattrice, have you managed to fix the Photoshop issue with the new drivers? I'm curious if the Photoshop 2014 shows the menus and icons in normal size, respecting the Windows scaling? Was Photoshop 2014 version the one shown with Surface Pro 3, or was it just a beta of Photoshop 2015? It was adopted to touch as well...

 

I suppose the scaling works now properly (bearing in mind Win 8.1 limitations, hopefully Win 10 makes things more customizable for multiple displays)?

Any chance anyone can help me locate a more up to date driver for my new Yoga 2 Pro? The above links are dead.

I'm currently running 10.18.10.3304.

 

I've found this...

https://downloadcenter.intel.com/download/24964/Intel-Iris-Iris-Pro-and-HD-Graphics-Driver-for-Windows-7-8-8-1-64-bit

...it refers to 4th gen core processors with 4400 HD graphics, is that us?

 

Thanks in advance.

Hi all,

 

I'm also trying to update my Y2P GPU from v.10.** to v.15.**...  and facing the same problems as xseon (see earlier post).

Thing is, when I download the Intel drivers (v.15.36.21.64.4222) as a .zip file, then uninstall all previous GPU drivers until only the 'microsoft default' driver remains, then update the driver manually through Device Manager, everything seems to go smoothly, only at the end of the day my driver is still v.10.18.14.4222 (same result I get with easy installer). 

Why is my machine refusing to update its GPU past v.10..., despite the newer gen of GPU drivers being out for over a year now? 

I've tried uninstalling old drivers, rebooting then installing new ones. I've tried doing the same process without reboot, or without uninstall at all. Everything gets precisely the same result. I've read the v.15 drivers will resolve or improve a couple of issues that i've having with my GPU, and yet the machine simply won't update, no matter how manually I attempt to force its hand.

 

Any guidance would be met with overwhelming gratitude...

Take another look at the Intel driver download page. You may spot that th description of the driver package shows the version number for the overall package beginning with the number 15. You may see that it goes on to list the version numbers for the actual drivers the package will install for each OS version the package contains drivers for. You will note that the actual driver version number in this package begins with the number 10 and I believe is the driver you have installed. You have the latest driver, it is just that you have misread the version number due to Intel's obscure numbering system.

So my hand was the one holding the hoops that I've been jumping through...

 

Kinda makes a guy feel foolish.

 

Thank you for shining light on this!!
