3D and performance

[Simon5CAE]

Hi, 

I've just updated to the new Photoshop but when I went to use the 3D in photoshop I couldn't and when I go into setting/performance this comes up below.. I reinstalled my driver but I'm still unable to use the 3D in photoshop. Can anyone help please.

Without any exact info about your graphics card model, driver version, screen settings, vendor-specific settings and so on nobody can tell you much. Those 64 GB only VRAM look fishy to begin with. That said, an R3 GPU at this point is pretty dated, so it may simply not be able to meet a minimum requirement.

There are several changes being made around GPUs.
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, 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
