System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: Intel(R) HD Graphics 530 Intel 4.4.0 - Build 21.20.16.4550

Blender Version
Broken: version: 2.82 (sub 6), branch: master, commit date: 2019-12-30 18:20, hash: 56ef761381
Worked: blender-2.82-b03066f7ee07-windows64

Short description of error
Blender does not recognize and use my Nvidia GPU. It only uses the integrated intel graphics card EDIT: for viewport open-gl rendering.

Exact steps for others to reproduce the error
On my system this can be observed in the Task Manager, by panning or orbiting around with the default scene.
The Task Manager shows 0% activity for the n-vidia gpu, for every blender version upwards form the working one mentioned above.

The following are the specs of my N-vidia GPU acquired from the working version if I were to report the bug via Help>Report a Bug link in Blender:
Graphics card: GeForce GTX 960M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

I also made sure I have the latest n-vidia drivers.

Regards,
Matej

I don't see a 960M in the list of supported NVidia cards (corrections welcome)

Did you select your card in User Prefs -> System ?

The Task Manager may not be representative of the situation, nor is simple panning around. Since the Help -> Report a Bug button does paste the NVIDIA GPU info, it stands to reason Blender does use that GPU. A better way to verify this is to use the Help -> Save System Info function and read the resulting text file (look for the OpenGL section).

Yes I have the card selected in User Prefs. It worked flawlessly till a few weeks ago till I noticed considerable lag in the viewport with heavier scenes and I started investigating.
I found the last working version from 12.12.2019, which is noted above. I doubt that the card wouldn't be supported - it is from a 3 years old Asus gaming notebook.

I probably wasn't clear enough, the N-vidia GPU pasted info is from the version of blender that worked from 12.12.2019. The latest versions of blender display only the info from my integrated intel GPU as it can be seen from the report above. I also found the last version that worked and pasted it in the worked section of the report.

@StephenSwaney The 900 series is supported. Any Nvidia GPUs from the GeForce 400 series and later are supported, if they're capable of OpenGL 3.3.

Just to clarify:

Do you do have GPU enabled in User Preferences -> System -> CUDA?
Do you have Device set to GPU Compute in render panel?

Yes, I have both enabled, but I am afraid that I wasn't clear enough that I am talking about the viewport performance, not Final rendering performance. Recent blender versions don't seem to be using my Nvidia gpu for viewport and UI.

Yes, I have both enabled, but I am afraid that I wasn't clear enough that I am talking about the **viewport** performance, not Final rendering performance.

Yeah, well. That is somewhat crucial, isn't it ;) There is "Exact steps for others to reproduce the error" section in the bug report form which is to be taken seriously, otherwise we will not be able to help.

Some more questions:

What is the render engine you're using?
Does the issue happen with any .blend file? Does it need some specific one? (Attaching simple .blend file where you can easily see the issue is a very good idea, as there might be some setting specific to your setup which will affect on the issue)
How do you verify GPU is not used? (If you use Cycles and use System Monitor's GPU utilisation - that wouldn't give you definitive answer because it does not include CUDA cores).

Also, please attach (as a file) system-info.txt generated by Help -> Save System Info.

Have you set your NVIDIA graphics card to be used while using Blender in the NVIDIA control panel?

Blender is reporting only the Intel(R) HD Graphics 530 Intel 4.4.0 - Build 21.20.16.4550 card being used for openGL aka EEVEE rendering in 56ef761381

As stated in the manual under troubleshooting,

Laptops
Laptops often have two GPUs for power saving purposes. One slower onboard GPU (typically Intel) and one faster dedicated GPU for a better performance (AMD or NVIDIA).
For the best performance the dedicated GPU should be used for Blender. Which GPU to use for which application can be configured in your graphics driver settings.

See my comment here and the following one about how to change this in Win 10.

Let us know if that works for you.

Triager Note: This appears to be simular to #72447 Did something happen between b03066f7ee and c6ba941339 that could be causing Blender to use integrated graphics instead of NVIDIA on windows laptops?

Thanks Evan Wilson, manually setting the N-vidia GPU in N-vodia Control Panel for Blender helped. The open-gl performance is back again and my N-vidia GPU is used again for open-gl viewport rendering . What bugs me I never had to do this before the blender version: blender-2.82-b03066f7ee07-windows64 from 12.12.2019.

The key point in my report that was missing was that the open-gl engines weren't using the N-vidia GPU, so I edited my report to make that clear and I learned my lesson - to Sergey Scharby.

Thanks for your time and effort.

The gpu chosen for OpenGL is a non-blender configuration.
This is configured in different ways depending on the GPU and operating system.
It is often set by the computer's power settings.

It would be interesting if we could pick the GPU from Blender preferences, but that's not a simple task given the compatibility of blender across multiple platforms.
Anyway, this is not a bug.
