Worked: N/A

Short description of error
On startup I receive error "Warning! Using result of ChoosePixelFormat." along with a popup starting "A graphics card and driver with support for OpenGL 3.3 or higher is required. Installing the latest driver for your graphics card may resolve the issue. The program will now close."

My computer is brand new. I have the latest drivers for my graphics card and all the latest windows updatees.

Open blender after fresh install.

Thanks - any help will be much appreciated! :)

Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Once Blender displays the warning, you can close it and the Windows Explorer should open and show you two files. Add them to your bug report by clicking on the upload button as shown in the screenshot below.

Thanks, Robert!

It only generated one file, which I have attached above.

For good measure I also ran blender_debug_log and have attached the analogous file.

See https://developer.blender.org/T72098#938719
and https://developer.blender.org/T72098#906441 for some workarounds.

Basically your computer settings should be such that Blender picks up Intel HD 630, not Quadro.

Brilliant, thanks Ankit - this has worked perfectly. And I can still render on the Quadro as normal.

The issue can be considered resolved :)

Can you tell which one of those worked?

Forcing "power saving GPU" option in the blender.exe graphics preferences.

In detail (in case it is helpful for anyone in the future):
Right click on desktop -> display preferences -> scroll to bottom -> graphics settings. Add blender.exe to the list of apps, then change the options.

@ankitm If this is a common problem on Windows that can't be fixed by Blender, then this should probably get documented in troubleshooting page of the manual.

@rjg I had commented it on that #72098 task about it. the compatibility settings workaround also helped 5-6 people.
but if it gets fixed, there will be less need for adding it. I havent used windows so I might be wrong in guessing how many people can find such settings.
@Alaska Could you please find some time for making a patch for this ?

@ankitm You're right, I didn't scroll far enough up.

Make a patch for what? Sorry I'm a bit lost and I'm having difficulty making sense of things.

Also, if it's a patch to the Blender source code, then sadly I probably won't be able to help much. I've never actually worked on the source code of Blender outside of modifying a diff created by someone else.

I wasn't clear enough.

#72098#912417

execute this program in mode of compatibility

Just wanted to note that this workaround has helped 4-5 reports of blender crashing in support chat channel this week itself.
That makes it a good candidate for addition to troubleshooting docs, if people don't know it already.

#77381#945121

@Ankit-1 (ankitm) If this is a common problem on Windows that can't be fixed by Blender, then this should probably get documented in troubleshooting page of the manual.

By patch, I meant a documentation patch which adds details of these two workarounds to the troubleshooting docs. (power and compatibility)

To me, it remains unclear how choosing the weaker graphics device and dropping the expensive NVidia graphics device can be considered to be a solution. I do not want compatibility mode, but rendering on the NVidia device.
