Photoshop doesn't detect GPU. Nvidia Geforce GTX 1650 with Max-Q design 4GB.

A bit of background on the video card :

There are several things at play here.
1. Adobe are updating the core graphics functions in Photoshop. This is driven by the operating systems of Apple and Microsoft in which the old Open GL/CL functions are being removed in the case of Apple, or deprecated in the case of Microsoft. This means that the graphics functions that have worked for years must be rewritten to use Metal and Direct X. At the same time, Adobe are sensibly updating those core functions to deliver the additional speed we require to handle the very large files of today.
2. Led by the changes being made above, Adobe introduced new GPU checks in 23.3.1. Unfortunately, these caused issues and have therefore been revised for v22.4. That means that many GPUs that incorrectly did not work in 22.3.1 will now be seen in 22.4 and will function.
3. Some functionality in Photoshop, such as 3D, still relies on the older Open GL graphics functions. To make these work, an additional preference Preferences>Technology previews>Deactivate Native Canvas has been added. This can be checked and Photoshop restarted to restore 3D functions to where they were in 22.3
4. Unfortunately, the move to update the core graphics functions will mean that some older GPUs will no longer be suitable. If you are using 22.4 and your GPU is still not recognised, first make sure the driver is up to date. If it is up to date, and you only have a single GPU enabled ( conflicting GPUs remain an issue), then you could try and force Photoshop to use your older GPU by creating a file PSUserConfig.txt containing the lines:
# Force GPU On
GPUForce 1
Save that text file to :
Windows: [InstallationDrive]:\Users \ [UserName]\ AppData\ Roaming\ Adobe\ [Photoshop_version]\[Photoshop_version]Settings\
macOS: //Users/[UserName]/Library/Preferences/[Photoshop_version]Settings/
Note though that this requires 22.4 or 22.4.1 and is not officially supported by Adobe, so may cause other issues – so you do it at your own risk

Also having this issue. Noticed because it disables scrubby zoom.

I have exactly the same problem. I'm on Windows with a 5700XT. Suddenly the GPU is undetected. Can only assume that its a bug in this latest version as it was working fine previously. Seems quite a few people are experiencing this. Unfortunately it means I cant use any 3D features which is annoying. I've reverted back to 2020 for now. Hopefully this will get fixed soon.

Hi! I had the same problem in version 22.3.1- "Unknown graphics processor". The only thing that helped me : get back to version 22.3

Almost the same problem in my notebook, with Nvidia Geforce RTX 2060.

The thing is, the first time I enter PS works fine, but if I exit and enter stops detecting, when I reset de preferences in the general dialog box, photoshops detects my GPU again, but when I exit again, and enter, it doesn't detect anymore.

So i thing is a bug whit the preferences, I couldn't find the file. 

Same problem here. It works fine on Lightroom, but keeps losing track of the GPU on PS. Will try to use an older version, now.

Why are you desperate? You have Photoshop 2020 version 21.2.7 to use. New release of Photoshop like PS 2021 version 22  are always released with many bugs.  Users report the bugs and it take Adobe months and months the get the latest version of Photoshop ready for massive users use.   With version 22 Adobe also upped Machine requirements for Photoshop use.   Many users will find that their current CPU or GPU or OS version do not meet Photoshop Version 22 requirements.  Adobe has changed  Photoshop version 22 GPU support and is having issues in their new GPU support code.  In each Photoshop version 22 update  Photoshop GPU support has changed,  Thought my Nvidia Quadro K2200 has been detected by all Photoshop 22 updates  GPU support has been different. In Fact I can not state that my  Nividia Quadro K2200 GPU will ever work well with  Photoshop.  Adobe GPU guide line state consider using a newer GPU that bench mark 2000 or better.  Older GPU may not be supported or may be of limited use. My Quadro k2200 benchmark is well below 2000.  Intelligent Photoshop users that require Photoshop for their work use Photoshop 2020 version 21.2.7. I'm not going to replace my machines just to be able to use the latest version of Photoshop on them.  That not in my budget.  Why are you desperate? Sky Replacement, refine hair, neural filters what new feature are you desperate for? How is your life ruined without these?

So my Quadro is 6 years old and does not benchmark 2000.  Works in Photoshop 2020 and prior version of Photoshop I have installed.  I'm not refining my hair its falling out. I'm not desperate, I'm 80, I'm slowing down some.

When Adobe get 2021 fixed your  2020 GTX should work it benchmark seems to be 3230..
