Premiere Pro CC 2014 - Choppy multicam playback

So I'm running Premiere Pro CC 2014 (8.0) on OSX Mountain Lion (10.8.5), using CUDA acceleration and everything works fine except for one thing: when I do a multicam edit I switch the program monitor into the multicam mode as usual. However, during playback I'm dropping frames with the video (audio playback is normal). This happens with playback at any resolution, even down to 1/8. Since I've retained the previous version of Premiere Pro (7.0), I've checked it's multicam playback and it's completely normal at full res. After going through and matching all settings in 8.0 to 7.0 I'm really at a loss with this problem, any ideas?

    As I stated earlier, the only solution I've found was to transcode my footage to DNX. With DNX footage I was able to do multicam with 8 angles with no lag. With ProRes footage it would bog down with only 3 cameras.

    I've been running into this problem as well on a brand new 15" Macbook Pro with the NVIDIA graphics card. When I bring the same project into CC14 on a late 2012 21.5" iMac, it's no longer a problem.

    Considering the SSD versus HDD, 16GB of RAM in the laptop versus 8GB in the desktop, improved graphics card, and i7 versus i5, I've been really frustrated by this problem. Not sure what would cause the disparity in performance as both are running the latest version of premiere.

    Running native 5D footage in multicam sequences with anywhere from 2-5 cameras and it's a problem in every instance. Would love for word from Adobe on this problem and seeing that it gets fixed.

      This is now a problem I have been having as well. I recently noticed it only with a 3 cam view and not a 2 cam view. I have tried the same project on multiple drives, disable audio and nothing works. The footage is ProRes 422

      I run: i7-3930k

      ram: 32 gb

      Well there's no problems with playback when the program monitor is in composite mode, although editing a multicam sequence in composite mode is essentially flying blind. Again, to underscore this point, this multicam problem IS NOT PRESENT in Premiere Pro CC (7.x), it occurs only in THE NEW VERSION (8.x). Can someone from Adobe tell us if anything is being done about this?

        For the record, the latest update of Premiere Pro (8.0.1) still hasn't fixed this problem.

        Hey

        I do a weekly multi cam job and I've noticed it only starts stuttering when there are multiple multi cams in a sequence that are longer than about 10 minutes each. My work around lately is to put each multi cam in sequence, do my multi cam edit, and then copy and paste each edited muli cam into the final timeline. Its very annoying but at least I can work this way. Also  I can tell after I'm about 8 or 9 minutes into a multi cam edit it starts dropping frames but it still workable. It needs to be addressed and fixed immediately!!!! I've re installed premiere, I've re formated my entire pc, and nothing I do fixes it. I can go into premiere pro cc 7.0.1 and cut a multiple long multi cams flawlessly so something has changed.

        The three cameras are native 5d and 7d. I'm on a powerful windows pc with CUDA and this only stated happening after the premiere pro cc December update last year.

        Also I turned off the multi cam reference monitor and that helped as well.

        I have the exact same problem. Multicam work perfectly until 7.2.2 then its been choppy and unusable ever sense. I don't know what to do.

        Just as an aside, I'm now getting more playback failures (little red X in bottom right) lately with footage that's already been rendered. This combined with the multicam issue, combined with ingest issues in Prelude CC 2014, leads me to think that whatever's been changed in regards to playback may be the cause of it all. Isn't Mercury Transmit a new feature in the 2014 release? If so, could that be the cause?

        I just wanted to add that this is occurring with multicam sequences of 3 or more cameras. If I go back to the source sequence with 3 cams and disable one then multicam playback is fine with just 2 cameras. The sequences I'm having the issue with look like this:

        3 cameras (with audio)

        All video is ProRes 422, 1080p @ 24fps

        1 audio track from separate recorder
