I just upgraded to CC 2015 and when hitting "0" , "SHIFT 0", or "Spacebar", I get the same result... A lagging play-back that is by no means 'real-time'. I also, tried cleaning all caches, restarting, etc...

Since both you and SolidDude are on Windows machines, go back to CC 2014 edition. It's slightly better.
Upgrade is an interesting word, with a very shallow scope of meaning. Adobe has yet to grasp it.
Same problem here on two iMacs 27" (brand new) and a MacBook Pro 15", all three running El Capitan.
Same problem here on a new iMac 27" 5k with 4GHz running El Capitan. Even small comps, e.g. 1000x1000 with half resolution will not playback in real-time after caching.
Yeah, I have a blank composition with NO layers it still doesn't play realtime! All audio and frame rates are stuttery. Why doesn't it play smooth once it gets through all of the frames? I'm having to use CC2014. I have a brand new mac retina laptop.
As a temporary workaround, try this. When you make sure that the timeline is not visible in the UI during playback, it most likely will play smoothly. This is somewhat awkward for polishing keyframes and timing interacively, but at least you can get a real-time playback for judging the animation.
Same issue here, my video and audio playback is not in real time. For the audio, the problem is huge, because I need to sinc with my animation.

Please, somebody know how to fix it?

Yep! hiding the timeline is the answer! No problems whatsoever, if timeline is hidden during playback. I have a 4K monitor and the larger the area of timeline that is showing, the more stuttery the playback. Phew, at least there is a workaround for now. I just have the render queue and timeline overlapping each other in a tab set and I just hit the render queue tab during playback, then click the timeline tab when i need to see the timeline again.
Well, the REAL ANSWER is Adobe fix it! It's very annoying, disturbing, is delaying all my works here. I have a full documentary with a 30 minutes of audio reference do sinc with images and motion graphics.
I'm using a brand new Mac Pro, very powerful. Is clear to me that we're talking about a software problem.
Adobe, please, please....solve it asap!!!
I did notice that if the timeline is not taking up too much of the screen, there is no slowdown. The timeline panel can run at about 1500px,800px with no problems. Any larger and it stutters. My guess is that their testers have cheap, small monitors, and this may have never come up in the QA stages. But still unacceptable. Having said that, I love the new timeline and I'm now used to it. Its SO nice to edit stuff and have the animation change on the fly. Definitely the right direction - especially since they added back in caching option, to make it more like 2014 CC.
Thanks a lot, this really works. Also, it seems that you don't have to completely hide the timeline, you just have to incrementally reduce it's size and keep testing until you get real time playback AND your timeline. Hopefully, it won't be too small by the time you get it right.
I'm on version 126.96.36.199 and the problem still persists.
