I have just noticed that I am unable to set my Pereformance preferences to use the Graphics Processor installed in my iMac, which is currently running 10.15.7

 

Having just updated to the latest version of Photoshop from Creative Cloud, I find that I cannot use the lighting effects filter as "Photoshop has detected an error with the adapter driver and I should reload the driver and try again".

 

However, if I revert back to Photoshop 2020, the graphics processor is switched on by default, as it has been for several years.

 

Is this problem a "feature" of the latest version of Photoshop and what can I do to get the Graphics Processor working with Photoshgop 2021?

The graphics card requirements have changed with the last two versions.

What graphics card are you running on your Mac?

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 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
