    major performance difference - OS X vs. Windows (CC 2014)

    john.l.stevenson Level 1

      I've built an Action-based auto-painter, using the Art History Brush Tool plus the Tool Recording option within the Actions themselves. The development work was done on an iMac machine. Recently I've also been testing the very same Actions on a Windows PC.

      Even though the specs for the two machines are very similar - and both normally run Photoshop CC 2014 in a very comparble way speed wise - the auto-painting done on the Windows machine is very slow. Completing the painting of a full 3000 by 2000 pixel image takes between 8 and 35 minutes using Windows. The same image can be painted in between one and a half and three minutes using the iMac. The averaged time-to-completion is approximately ten times faster for the iMac.

      The actual specifications for the machines and the software preferences set are:

      iMac

      3.4 GHz Intel i7 processor

      16 GB RAM

      conventional HDD 1 TB

      ATI Technologies AMD Radeon HD6970M 2048 MB

      OS X 10.9.4

      Photoshop CC 2014

      - set to 75% available RAM

      - set to 20 History states

      - set to 6 cache levels, tile size 1024 kB

      no other primary application open

       

      Windows PC

      3.3 GHz Intel i5 processor

      16 GB RAM

      SSD Intel 120 GB

      AMD Radeon HD 6950 1024 MB

      Windows 7 Pro (SP1)

      Photoshop CC 2014

      - set to 75% available RAM

      - set to 20 History states

      - set to 6 cache levels, tile size 1024 kB

      no other primary application open

       

      Does anyone have any suggestions on what might be causing the performance difference?
