    Graphics Processor Settings for CS6 and new iMac

    Husky99

      Just got one of the brand-new 27 inch iMacs a few days ago, one with the NVIDIA GeForce GTX 680MX (2GB GDDR5) video card.

       

       

      I'm using Photoshop CS6.

       

       

      Every time I enable Photoshop to take advantage of the video card for additional memory - Preferences > Performance > Graphics Processor Settings - I run into constant problems.

       

       

      Constant delays, is the better description.

       

       

      I'm talking about the "colored spinning wheel" icon appearing just about every 30 seconds and holding me up for about just about the same period of time.

       

       

      Turning off the use of the video card solves the problem every time.  No "colored spinning wheel" icon appearing - ever.

       

       

      I got the larger video card hoping to take advantage of as much available memory as possible; unfortunately, it looks like there seems to be a problem with the interaction between Photoshop CS6 and the video card's driver.

       

      I've got all the latest updates for both the Mac OS and Photoshop. Any ideas?

          Do you have the latest update for Photoshop?

           

          That's a pretty new video card...  It may be that you need an update from Apple that's not yet available.  Be sure and let Apple know about this problem.  They're likely the ones who will have to fix it.  Until then, can you drop back to Normal or even Basic mode to recover functionality?  Adobe provides those settings as alternatives for when something isn't working.

           

          You mention "for additional memory"...  You are not changing your Photoshop max RAM limit in anticipation of the VRAM helping or something along those lines, are you?  VRAM and RAM are used for entirely different things.  Unless you're doing 3D work that video card VRAM isn't really going to help you with much in Photoshop.

            Good to know. Thanks!

             

            I will be sure to report the problem to Apple. I will also double check to make sure that I have all of the latest updates for everything. (I ran this check about 36 hours ago, but will check again.)

             

            In association with this Adobe-Photoshop link, it notes the following takes advantage of the video card:

             

            • Scrubby Zoom
            • Heads-up display (HUD) color picker
            • Color sampling ring
            • Brush dynamic size and brush hardness control
            • Bristle Brush preview
            • Rule of Thirds crop grid overlay
            • 3D overlays (including ground plane, light guides, and bounding boxes for mesh and materials)

             

            Because I use (regularly) a couple of Photoshop third-party add-ins (Nik software), I was never sure if they could take advantage of the video card. So I just decided to go ahead with the larger video card just in case.

             

            By the way, Nik Software's sales department said they didn't know if their add-ins would be able to use the video card; they suggested contacting technical support to answer that question. However, I wasn't going to wait 15-20 minutes on hold just to speak with somebody (too busy of the schedule lately). So again, I just decided to go forward with the larger video card.

             

             

            Thanks again.

              I don't think it's a bad choice; if nothing else it's somewhat future-proof.  I have a 2 GB video card myself (ATI 7850).

               

              I don't have Nik plug-ins, but do they say they use OpenGL or OpenCL to accelerate their operations?  If so, the powerful GPU will be a help.

                I was able to do a little bit of investigation during the past 20-30 minutes on Nik’s website. Found out that 3-4 of their major plug-ins do indeed use the video card; fortunately, at least for now, the two plug-ins that I utilize do not.

                 

                Perhaps this will change in the future; perhaps they will decide to use the graphics processor as well on these plug-ins I utilize on a daily basis. Hopefully by that point in time I will have been able to clear up this problem.

                 

                Thanks again!
