Photoshop 22.3.1 says Unknown GPU

While Photoshop 22.3.0 awkwardly takes a bit of an extra step to properly load Advanced GPU settings, version 22.3.1 entirely broke GPU support for me. After updating today, Photoshop failed to load my NVIDIA GTX 1050 Ti graphics card, saying “Unknown GPU” with “Use Graphics Processor” dimmed and unchecked. I tried restarting both Photoshop and my laptop but no luck. I already had the latest NVIDIA driver 461.92 installed prior to updating Photoshop. Rolling back to 22.3.0 returned everything back to what it was like before installing the latest PS update. I understand that my GPU is already a few years old, so I considered the possibility that Adobe might have all of a sudden dropped support for it, but that would be a really terrible change to make in a minor version update if that’s really the case here. I hope it’s only a bug that would be fixed in a new update.


Here’s what it looked like in 22.3.1

We are aware of an issue where Photoshop 22.3.1 is not properly detecting the GPU, and have a fix that will be available soon; thank you for your patience.


An earlier version of Photoshop may be installed and used for the time being, or 22.3.1 should work fine for most features, since there are CPU fallbacks for everything except 3D features and the Oil Paint filter on Mac.


Again, thanks for your patience as we stabilize GPU usage. This will ultimately be an important step forward to boost performance across the application.

What causes the error ‘Photoshop has encountered a problem with the display driver’?

This error message only occurs when Photoshop is unable to access your graphics resources for its operations. The reasons why it is unable to access can vary computer to computer. Some of the causes are:

  • There is a conflict with your onboard and dedicated graphics installed on your computer.
  • The graphics sniffer program of Adobe Photoshop is not working properly and fails to retrieve details of the graphics hardware installed.
  • The application is not installed in your system directory which may cause issues in permissions in accessing the graphics resources.
  • There is a problem with your graphics drivers. If the drivers are not working properly, no application will be able to use the resource.

Before we start with the workarounds, make sure that you are logged in as an administrator on your computer and have an open internet access.

Solution 1: Disabling ‘sniffer.exe’

The executable ‘sniffer.exe’ is an application which detects the graphics modules installed on your computer. It detects your graphics resource and passes the information on to the application so the resource can be utilized. The sniffer can sometimes go into an error state which might cause Photoshop not to detect any hardware. We can try moving/rename it and see if this fixes the problem at hand.

  1. Navigate to the directory where Photoshop is installed. The default directory is:
C:\Program Files\Adobe\Adobe Photoshop CC 2015.
  1. Once in the directory, search for the executable ‘sniffer_gpu.exe’. Cut it and paste it to some other location (such as the desktop).
  1. Now restart your computer and try accessing Photoshop. Check if the error is resolved.

Solution 2: Disabling onboard graphics (if dedicated graphics installed)

Another workaround which was reported by users was disabling onboard graphics if dedicated graphics (such as AMD or NVIDIA) are installed on your computer. It seems that Photoshop has issues when two graphics options are available and it fails to make a choice which one to use for its rendering and operations. Before following the steps, you should verify that your third-party graphics card is functioning properly.

  1. Press Windows + R, type “devmgmt.msc” in the dialogue box and press Enter.
  2. Once in the Device Manager, navigate to the entry “Display adapters”, right-click on the onboard graphics and select Disable device.

  1. Now try accessing Photoshop and check if the error message is resolved.

Solution 3: Changing directory of Adobe Photoshop

Another hiccup which Photoshop faces are the permissions if it is installed on another directory. Whenever an application is installed in program files (the driver where the OS is installed), it gains all the basic permissions automatically. If your Photoshop is in another directory, we can try changing its directory and see if this fixes the issue. If simply changing the directory doesn’t work, you might need to reinstall the application to the targeted directory.

  1. Press Windows + E to launch Windows Explorer. Once in the explorer, navigate to the directory where you installed Photoshop. Right-click on the folder and select Copy.

  1. Now navigate to the driver where your OS is installed (by default, it is Local Disk C), and open your Program files. Paste the application there.

Fix Photoshop Unknown GPUP :Not detecting older GPU’s

Not sure who beta tested this version or if Adobe’s QA went on vacation during the pandemic, but this release is one of the worst we have seen!

Aside from the slower performance, there is a major flaw in screen redraw. And yes, I posted a bug report this morning…just curious how many others are seeing this issue.


Everyone in our staff updated last week and can reproduce this problem on various machines (laptops, desktops) under Windows 10 using different nVidia video cards and drivers. We even updated to the latest nVidia driver this morning (released today on June 24) and it still happens.

Basically moving any object pasted from Illustrator (bitmap or smart object) leaves an imprint of the image (screen redraw issue) on the background layer and/or will cause other artifacting on the artboard and over various UI panels. Zooming in and out to refresh the screen does not fix this. Toggling the layers off and on will show what is happening (see the video).


I posted a bug report on this so hopefully Adobe tech support can respond with either a workaround or release a patch soon! It is driving our graphic artists crazy. It did NOT happen last week with the previous version.

Posting a screen recording and some screenshots.


We are running Windows 10 64-bit with various nVidia cards. Toggling the “Use Graphics Processor” on or off does not make any difference other than the full object shows with it on, and random lines and artifacts show with it off.



Photoshop’s GPU requirements have increased for 22.0. Try the solutions here:


If your card is not supported you may need to upgrade your graphics card.


For example @ged’s card is very old and is not supported: 


It scores less than 200 on this benchmark: 


More modern cards that have been released in the past year or two that score in the 2000s and 3000s can be had for $100-$150 (see the same link above)
