Graphics processor usage problem after reinstallation

Aug 7, 2012 4:25 AM

Hi!

I recently installed Photoshop CS6 and had no problem what so ever the first week.

Due to an incident I removed Photoshop and reinstalled it. Now I'm having problem with GPU acceleration.

 

My computer has 2 graphics cards, GeForce GTX 460(Primary screen & projector) and GeForce 210(Secondary screen).

Photoshop detects my GTX460 and uses it. But when I move Photoshop to my secondary screen I can't see any documents.

It's just a gray screen.

 

I had Photoshop CS5.5 installed before and had no problem using my secondary screen, installed PS CS 6

pararell with PS CS 5.5 and had no problem.

Then I removed PS CS 5.5, still no problem.

Reinstalled PS CS 6 and it doesn't work.

 

It obiusly worked a few days ago with this set up, and now it doesn't.

I might also ad that unchecking Use graphics processor help fixing the problem.

But I wanna have all the nice GPU features.

 

What can be the problem?

    How did you remove it? Manually or did you properly uninstall?

    Have you tried the banal trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)?

    Photoshop does not support 2 graphics cards.  Almsost all modern cards will support at least 2 monitors, so 2 cards are not necessary.

     

    Disable the weakest card and think you will do just fine.

    +1 to what Curt said.

     

    FYI, many modern graphics cards support 3 or even 4 monitors.

    The problem is with running multiple different graphics cards.

     

    You're not going to be able to make such a setup work reliably with Photoshop.

    It may be more luck than design that the setup worked for you.  Even the Adobe engineers have posted that Photoshop does not support 2 graphics cards.  And like Noel said with 2 different cards you are really stretching your luck.

     

    CS6 puts a lot more stain on a GPU so that may be one reason why you are having more problems.

     

    Computer hardware and software are great, but at some point you are best served to accept Reality rather than rely on Hope.
