For me the audio's first second stutters a lot and it's hard to maintain real time fps. The audio problem sounds like it's skipping some parts of the audio right at the start of the playback, so say you got a 10 second loop, it sounds like a mediaplayer stuttering loop, not a real constant loop. I do TV commercials with tight deadlines and I can't sync audio listening to this weird stutter with wav audioclips. Computer specs win7, gtx 670, i7 4770k 16gigs of ram. So i use After Effects CC 2014 in the mean while.
