    No real time RAM preview with Pr CS6.0.1 Open, Real time RAM preview with Pr Closed

    RBemendo Level 1

      When Premiere is closed I see real time performance on RAM previews (29.97fps), smooth UI interaction with and without Fast Draft enabled.  When Premiere is opened I get poor fps in RAM previews, lagging UI interaction unless Fast Draft is enabled.  Premiere Memory preferences are set to 6GB reserved for other apps, and Optimized rendering is for Memory.  It seams that as soon as Pr takes on any processing AE's performance just dies until Pr is closed. 

       

      I've tried clearing caches in AE and in Premiere, restarts, and repair disk permissions,

       

      Included is a realtime screen capture of what i'm experiencing, I open and close premiere twice to illustrate that it's not an isolated occurrence.

       

       

      any ideas?
