    Why is Premiere CC 2014 v8.1 playback choppy?


      I've been working with Premiere v8.1 for about a month and its slowly becoming more complicated to work with b/c of playback issues. The more I edit with more media and audio with transition effects, fast premiere color grading, and even render (to a green line), to more choppy the playback is. I've dumped my cache files and it only work once or twice on play back for a couple seconds then eventually became whole choppy again. Below are my specs:


      Mac Pro 1,1

      Lion OS X 10.7.5

      Premiere v1.8

      10 out of 250GB SSD Start Up (programs only)

      I've never hand problems in CS 5.5 version of Premiere even when handling RAW RED 4K footage playback at a low res setting in playback settings with just 7 GB, so its hard for me to understand why its acting up with just prores footage in a more updated Premiere with matched media settings. So what can I change in the settings to make this work?
