Since 22.3.1 (and 22.4.0) my GPU is not reconized in PS.

It was ok when the version was 22.3.0.

Does someone with this configuration "AMD Ryzen 7 4800U with Radeon Graphics" can tell me if it works ?

Thanks.

I cannot test it for you, as I don't have that system, but can give some background as to what is happening with GPUs. It sounds like your integrated graphics do not meet the current system requirements, which look for a minimum of 2GB GPU memory, with 4GB recommended.

 

https://helpx.adobe.com/photoshop/system-requirements.html

 

Some background:
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 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 (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 is requires 22.4 and is not officially supported by Adobe, so may cause other issues – so you do it at your own risk.

 

You could try step 4 but you may experience crashes when the GPU functions are called. Personally I would try it and see.

Dave, your solution (step 4) works correctly.

What do you mean by "you do it at your own risk" ?

The risk is very high ? If I note an issue, I only have to remove the .txt file, right ?

You could experience instability or crashes. If it doesn't work just remove the text file
