          Is this happening while its caching or has it already cached (that is, is the green line over your timeline)?

          What, exact, version of AE CC 2017 are you running? Is it 14.2.0?

              Are you new to After Effects? Are you using one of the default presets for composition settings? What is the frame rate of your comp? What kind of footage are you working with. What kind of effects are you using? Without details it is impossible to tell you what may be wrong. The slow preview rate may well be completely normal for your project. I have some comps that take as many as 7 minutes a frame to render at full resolution. I have others that render at the rate of several frames per minute.

                  After Effects will usually not play things through smoothly until it's been cached. After Effects is not like a video editing program. Premiere Pro, for example, will just play through video and audio files quite smoothly without needing to cache anything (assuming no effects have been applied), but AE doesn't work that way.

                   

                  Now, in recent versions of After Effects this has been improved, but generally speaking After Effects needs to cache a preview first before it can play it back. This is one of the biggest "gotchas" that bite newbies in the butt if they haven't gone through a decent Getting Started course.

                   

                  Speaking of latest versions, have you considered updating? The latest version is 14.2.0.x

                   

                  Anyway, here's an example. Here is my timeline as I'm working in a project. Note that there is green over the frame I am on (AE has rendered that frame to show it to me in the composition window), but there is no green anywhere else. If I hit play, it will be jerky and slow as AE renders the frames:

                  Now that I've cached the preview, there is green over my whole timeline and I can play it back real time:

                  0nocache.jpg

                  There are settings in your preview panel you can mess with to change how AE does previews (and you can specify different behaviors for starting and stopping with different keys too).

                   

                  You really, really need to go through some getting started resources to understand how all of this works. AE is way too complicated to try to use it without a solid foundation first!

                          The green line will appear over your timeline as you play your preview. It will be choppy and slow, but then the next time it goes through, it will be much faster. It is probably best to check small sections of a few seconds long by adjusting your work area.

                           

                          Again, this will all be covered in a good "getting started" course.
