Hello everyone,

I have a very big problem !
My PC specs are : 64gb RAM , core i7 6850k, GTX 1080 Ti 11gb, 500gb SSD ,Windows 10 pro
I Have After Effect 2017.2
My problem is that when I'm working on a video or something i click on space-bar (to preview my work), But it doesnt start normally it usually tells me that the FPS is 15 fps and it lags too much!
Although i give the adobe applications 50gb RAM and I enabled CUDA for GTX 1080 Ti with 8gb of Texture Memory and Ray Tracing is on GPU and Disk Cache is 100GB
Please Help me!!
Thanks

I think the only big problem you have is lack of AE knowledge. 

First, you can NEVER expect to work like a video editing application,  where you just press the space bar and everything plays back in real time. AE IS NOT A VIDEO EDITOR.  It's an effects, compositing and motion graphics application, used for very different purposes than a video editor,  It functions differently than a video editor. Particularly in the way you view your work -- you don't play, you PREVIEW.  tOTALLY DIFFERENT.

I encourage you to go to AE Help and look at the section on Viewing and Previewing.  There are a WHOLE lot of ways to preview that can help.

A good deal of quality time spent here won't hurt, either.....

Exactly which video on this help page is supposed to help?  I have the same problem.  I'm not looking learned everything before I can learn something.  And, I am NOT pressing the space bar.  I push play.  The video sometimes stops and replays the same section but always it says not in real time.  The video was created in CS5.  I am using CC.  I seem to see this when the original video is somewhat sophisticated in its effects and not for simpler videos.  Again, I'm not looking to study everything on the help site.  I am looking for straightforward help with what should be a common and obvious issue with playback.

You set AE to cache frames for preview. You hit the zero key on the numeric keypad.  AE previews as much as memory & cache will allow and as fast as they'll allow.  This ain't a video editor, Sparky.

So Dave, question. Being as it is that AfterEffects is not a video editor designed for real-time editing, than how do motion designers and animators properly test their animations if they can't see them? How do professionals know how to distance key frames so that they play back organically? Is it just experience, lots of exporting and testing, or another specific method? I'm a graphic design student and I'm just learning the ropes here.

If you work on timing, there is no need for a crystal clear image, if you work on imagery, there is no need for realtime playback.

Most of the time, I work with quarter resolution, sometimes I also skip frames. Also, I use the render area a lot. Mostly it is just a few seconds, sometimes even just a few frames. I press 0 on numpad to render this area only and watch the preview of this part, alternate the values and watch again until I'm happy with the result.
