Editing a series for Fox - weird behavior from our system since Premiere CC 2014.2 Update

Question

Hi all,
I'm cutting a series for Fox and we're on season 3. I cut all of season 1 on FCP7. Then dipped my toe into Premiere waters between seasons and cut all of season 2 in Premiere with excellent results. My only gripe on the previous Premiere CC versions was towards the ends of cuts when my timelines were rather complicated, I'd have a crash or two each day. Well I'm finishing up an episode this week which is the first I've cut in version 2014.2. It's WAY more stable, I haven't had a single crash in weeks. That part is amazing! The huge downside has been that my real time performance seems to have taken a serious hit even though the hardware, disk storage, video card, tower etc. are all identical. Worse is that when I'm playing back a sequence that's longer than one show act (like a sequence with the entire show in it, only 22 minutes) I'll a lot of time get a slight stutter frame between edits and that happens on a lot of edits. It's a fast paced racing competition show so say I'm playing back my timeline with a cut from a go pro on the steering wheel to a shot outside the car, it looks like there's a freeze frame of 2 frames long at the end of the GoPro shot before going to the shot outside the car. It's not only going from GoPro to non GoPro, it seems to happen on any kind of footage UNLESS I render it all, then it's fine. It's very frustrating. I've also confirmed when opening up an old show that played back fine on the previous version that this is still happening on these old projects as well. Also when color correcting in a sequence, there's generally a delay in seeing my color changes of several seconds! Premiere has always been instantaneous or very close to instantaneous when showing color updates for the past year until this update. Is this a known issue? Here's my specs:
Premiere CC 2014.2
Mac Pro 2009 2.93 Octo
32GB Ram (in my memory settings of Premiere, I have it set to optimize rendering for Performance and 26 GB RAM for Premiere, 6GB for other apps)
GeForce GTX 780 6GB version
My media is attached via a GRAID 4TB drive connected via eSata. I've also tried a different Graid attached via USB3 and another hard drive connected via FW800.
OSX 10.9.5

Answer 1

Hi, I had the same problem.
What I found is the audio external interface needed to be reset.
So I've did this : quit Premiere, unplug my USB audio device, plug it back and launch premiere.
Every was fine.
Hope it work for you.
