Fix some applications not running on laptop GPU
Hi since the Windows 10 Anniversary update games or utilities i have in Steam valve dont seem to use the GPU on my laptop but instead use intel graphic the laptop i have is a Lenovo Y50

The change is needed in the operating system kernel mode graphics driver. Microsoft is looking into scheduling this development. In the meantime, provided you have purchased a platform allowing you to, the workaround is to disable the low end GPU so Windows uses the only one left. Today, Windows will always use the POST graphics card.

Thanks Daniel, but that's not a solution. That's called a workaround.

*SOLUTION*
I had this issue as well but have discovered a solution. If your laptop has any form of appropriate video output (I have a Dell XPS which uses HDMI) you can use an HDMI or other appropriate cable to connect the output to one of your monitors and use the DisplayLink docking station/connection for the other. This will restore your laptop's ability to use the discrete GPU and run GPU-intensive applications such as SketchUp, Revit, etc.

@AdamH, because the other option doesn't used the Microsoft IndirectKMD as it's not an indirect display.

I have read these comments as I am testing a new dock, I like that it has DL for my USB3 laps I connect but I connect my MSI GS63VR I have the same issue...you claim the issue is with Windows Kernal but I have a USB-C dock (no DL) that I get full framerates...but then swap to a DL enabled USB-C dock and get low framerates. curious as to why there isn't a passthrough or a bypass...2 docks connected with USB-C one with DL one without both Lenovo docks....USB-C direct works USB-C DisplayLink doesn't?

Would just like to state, this is still a problem. its 2018. come on.
Windows 10 Pro N
nVidia 860GTXthis use to work on Win7 pro. I was able to put display port onto the nVidia chip and go about my way. Now, im having tons of lag issues. Need that win in Fortnite. Can't get it. Video is too slow.

Are you going to fix this or what? How many years have this problem been lingering? What did you think while creating the product, did you not think anyone will need to use their Nvidia GPU at all? Can someone, at least the product manager who over 2 years ago wrote that they were looking into this issue provide an update if it won't bother you too much?

Okay, it doesn't apparently show e-mails....I'll try to keep an eye on the thread.

I'll try to keep an eye on this thread but feel free to e-mail if you have additional concerns. Hopefully this will help us all cope while Microsoft gets its act together regarding kernel drivers.

I got this problem today, upgraded from win 7.
I have Lenovo P50 with Lenovo USB 3 ultra dock at work using Autodesk programs, Revit mainly.
Is there any solution in this problem?
Are Microsoft working on it?
Does it work to start program before using the dock, it shows that the nvidia GPU is used but is it faster? -

I have this problem also, is there a solution?

Any update on this? I've run into this problem as well, and disabling the intel graphics card prevents the external monitor from working at all.

@Jan, you can subscribe to comment notifications, as far as I can see from my end.
What is a CZ entry? There was a bug report and the rest was during meetings.@ckoroglu The issue here is about Windows and their kernel graphics driver. Linux doesn't use Microsoft kernel graphics driver. Linux doesn't have the notion of "indirect displays" either. That's a Windows feature.

Did anyone ever get this fixed? Stuck using this dock at work and getting rendering issues and a disabled nvidia GPU still...looks like 1 year later this hasn't been resolved?

Sorry, as there is no mail notification here I only get to this page occasionally. Forget about the 9200 build, I'm on latest 16299.19. The perftool reports the version wrong. But in the last message I only acknowledge there is no workaround possible. Even I'm able to force the app to use the NVIDIA card for compute operations (I see it on perf chart for many other applications, including the NVIDIA SDK samples) the overall graphical performace is very poor in this setup ... it's even worse compared to using the POST graphic board only. No chance without MS fix. It's a painful issue as many tools do not work at all (I could live with it if they were just slow). The feedback hub is divided by markets, I'm not able to upvote the current issue. Any clue whether there is a CZ entry yet?

Jan, this report says Windows 8.0 (that's the build 9200). This discussion is about Windows 10 Anniversary Update onwards. If you're really on Windows 10 and the graphics tool reports Windows 8.0, I wouldn't trust it understands how the Anniversary Update graphics subsystem fundamentally changed the deal and how it can measure things properly for something it doesn't understand. If you are really on Windows 8.0, I don't see us doing any new development for it as almost no-one uses that OS (~1% maybe). Could also be the OpenGL bug on the Intel graphics driver affecting your tests.
Feedback about the OS using the GPU from POST is not a DisplayLink opinion, this is a Microsoft graphics team affirmation. They wrote that part of the feature. I am inclined to believe both the author and general test feedback.

I did a couple more tests. It seems the application when started in "direct - no DisplayLink" and then switched to DL still uses some GPU functions (and reports itself as using NVidia GPU) but it is switched to the internal board framebuffer. I did following ... used the personal edition from https://benchmark.unigine.com/valley, first run it on notebook itself. Then I have attached DL monitor (with benchmark running) and did the second round. Then i have restarted it and run third round in standad DL configuration. Here are the results:

On the other hand it displayed GPU parameters and guess which GPU it reported .. NVIDIA. And not only that, even the GPU temperature and clock frequency were shown in the (b) scenario and they nicely reflected the scenery complexity. The NVIDIA GPU was not idle.
My feeling is the GPU is still used in B) scenario but pixel data are block-copied to onboard framebuffer. Not very surprisingly this gives the worst results. So this idea is probably a way to nowhere :( and the only option is to wait for Microsoft to resolve it.

Hello Alban, the Win10 1709 version of Task Manager show the utilization of available GPUs. I tested it with Autodesk Fusion360 ... even after I reconnect the DisplayLink monitor the 3D operations in the application are immediately reflected in the NVIDIA GPU performance graph. Second - integrated Intel graphic does not support 3D acceleration required by Virtualbox. Attempt to request it triggers an error message if working on docking station using display link. If I start the virtualbox first and then connect USB monitor, I can enable the acceleration without any warning. I'll try to record it.

Hell Jan, how do you check what GPU is used? I am rather inclined to believe Microsoft graphics engineers who told me the kernel driver doesn't change on the fly and that they won't change until they receive feedback from Windows 10 users.
https://aka.ms/Cojpi9 is a Windows 10 Feedback Hub entry from someone about the graphics card selection for Windows 10 v1709.

Just a note to this frustrating issue (it's not "only" about gaming but tools like Virtualbox are also affected and really hard to use now) ... I understand the point with card selection, however this is surprising: if you unplug DisplayLink device the system start to behave as expected ... using say NVIDIA for configured application. However if you connect the DisplayLink monitor AFTER the particular software was started it happily runs on the DisplayLink monitor utilizing the high-end graphics card. If you shut the program down and restart it with DisplayLink active it falls back to the integrated graphics. Could not this be used to some workaround (beside disconnecting monitors before application start)? I'm on 1709 update. Thanks for any advice.
