Photoshop CC Does not Recognize NVidia GT640m

Oct 21, 2013 1:42 AM

HI,

 

I am running a Dell XPS laptop (Windows 8 Professional) with the following graphics:

 

Intel HD Graphics 4000 &

Nvidia GeForce GT640M

 

I have Photoshop CC installed (14.1.2) and everything is fine using the NVidia driver version 314.22, however when I try to update the driver to the latest version 327.23 (released 19 September 2013)  Photoshop does not recognise the GT640M and will only use the Intel HD 4000!!!!

 

Is anyone else having this issue or know a solution?

 

Thanks in advance

    Photoshop uses the GPU to improve performance of some operations. A program using the GPU can crash if the GPU is outdated, if its driver is outdated, or if the particular computer/GPU combination is uncommon or unverified. In order to avoid crashing, Photoshop uses a small program called the sniffer to assess the GPU before Photoshop uses it. If the sniffer tells Photoshop that the GPU is unsafe, or if the sniffer crashes, Photoshop will not use the GPU. Photoshop's decision is visible in the Performance Panel of the Preferences, where you will find the Use Graphics Processor checkbox unchecked and dim. The first time Photoshop decides to disable the graphics processor, a dialog is shown.

     

    If you could run the sniffer manually and post its output, that would help diagnose the problem. Here's what you do on Windows.

     

    1. Open a command prompt. On Windows 7 Click on the Windows menu at the bottom left of the screen. In the type-in box in the menu that pops up, type "cmd" without the quotes and hit enter. On Windows 8, click the start/Windows key and type "cmd".

    2. Run these commands. You may copy and paste them one by one into the command window or type them by hand. To paste into the command window, right-click in the title bar, and choose Edit>Paste from the popup menu. The first two commands navigate to the place where Photoshop.exe lives in your installation. Alter them as necessary. The last command runs the sniffer and places its output in a file called sniff.txt in your home directory.

       c:

       cd \Program Files\Adobe\Adobe Photoshop CC (64 Bit)

       sniffer -verbose > %USERPROFILE%\sniff.txt

    3. Send the sniff.txt file to me in an email. Please include a description of your configuration: how many cards and monitors, which monitors are connected to which cards, and which is your main display. If the command above produces additional error messages onto your command window, please copy/paste them into the email. To copy/paste from the command window:

       a. Right-click in the command window's title bar, and choose Edit, then Mark.

       b. Drag-select the text from the command down to the next command prompt.

       c. Press the Enter key. This copies the text into the clipboard. Now you can paste it into the email.
