I have windows 10 laptop with AMD Ryzen 5 and Radeon Vega Graphics. Since the recent updates I can no longer use the liquify function to recognise a face. The only way I can do this is by going back to Version 22.3 which means that I am missing out on new features. Can anyone help me to deal with this? Simon
First off - Is your graphics card driver up to date? Check with AMD, don't assume that drivers delivered by Windows updates are correct or up to date. This is still the most likely reason for a GPU nor being recognised.
The second check is that your system has more than one GPU a discrete GPU and an integrated GPU. If that is the case see sections 7 and 8 here:
If you have ruled out the above then some background and a possible action (under 4 below may help)
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
