Choppy preview playbck (even when rendered)
I’m the production manager for a commercial production house. I’ve got a new employee moving on to a computer that was used by a previous producer. I’ve decided to take the opportunity to smooth out any technical issues (since we’re starting with a new user account and can clean out prefs, etc). While I’ve been training her, I’ve noticed that the video playback is just AWFUL, far worse than on my computer, even though her’s is newer, has a better GPU and faster processor.
Video will only play smoothly for about 2 seconds on the timeline before going completely jerky. What’s stranger is that rendering makes no difference… red line, yellow line, green line… all choppy and jerky. After about 2 seconds of playback it starts to skip frames, after about 2 more seconds we’re talking 1sec freezes. We haven’t made any changes to the system. The prior employee complained about it too, but I didn’t have enough first-hand experience to realize how bad it was.
The files are AVCHD 1080i60 most of the time (sometimes XDCAM, sometimes 24p variants), edited on an AVCHD timeline. But that shouldn’t make a bit of difference when I’ve done a full render preview.

Hi Eric,
You should definitely use an external USB3/ESATA drive at the minimum for playback. That may be your issue. A full drive would make things worse.
If that doesn’t solve it, check your hardware settings for missing or incorrect drivers, finally, do a clean OS install.
Also, you may want to look to at least doubling the RAM, especially with CS6 or CC.
