CC 2015 Previews Not Real Time
-
Hey Simon, I am facing the same issue! You are not alone.
What also really drives me nuts is the fact, that when you have your time indicator let’s say on the first frame and the next two seconds are already rendered, I could’nt find a way to render past the second second before the preview actually starts. I hope you could understand what I mean^^ -
The biggest issue that I have not seen addressed here is the Live Preview does not use the GPU at all. It only uses the CPU which is frustrating to have a card with 6GB of VRAM and not being able to use it to obtain realtime playback. At first I was excited about Live Preview because I thought it would be more like Premiere Pro where you can layer multiple tracks and play it all back in real time with a workstation card such as the Quadro 4000 or FirePro d700. But in reality its like stop motion animation. Only after you render it (not preview it) can you actually see what your results are. We should all post to the Adobe Forums that we want GPU accelerated Live Preview in hopes that they will add this feature in an update.

Posting in the Adobe forums won’t be as useful as filing feature requests! They actually track feature requests. Posts in the user-to-user forums don’t get tracked.
Be sure you specify in as much detail as possible how you would like it to work. If you were paying attention to Apple’s latest WWDC, there was an Adobe demo showing GPU-accelerated effects using Apple’s Metal. Adobe has said in other places that they are exploring options for using the GPU in the future.
AE has always been CPU-based, the only thing it’s ever used the GPU for was the short-lived ray-traced renderer and, of course, third-party plugins like Element, ShapeShifter, and 3d Invigorator.

I just submitted a request. Perhaps if enough people do they will make it a priority.

The preview speed is horrible in CC 2015.0.1 (updated version). It used to be a lot faster in CS6 and 2014. Isn’t the new versions suppose to be better and faster? Why is after effects flying backwards? 🙁
Element 3D preview and render causes the after effects to crash. The same project on the similar machine using CS6 performs well. (No crashes)
I’ve already reported the bug. Hope it will be fixed in the next update.

Simon, I didn’t read through all the answers… so I’m sorry if this has been adressed already.

MAybe the cause is VERY simple… did you check if your quadro and the Tesla are in fact ENABLED after installing CC15.
I am using a Nvidia GTX 780Ti with an insanely high CUDA performance. But it shows up as unsupported.
I first had to manually enable it at
PREFERENCES> PREVIEWS> GPU INFORMATION > CHECK! Enable untested, unsupported GPU.This might help!

woooaaah! Thank you man!
Actually it was tunred off in my case!
Really hope that rendering gets better now.
Thank you so much. -

The Ae team is doing a lot of work to modernize After Effects. For Ae CC 2015, rendering has been separated from the UI for the first time. This required major re-architecture work, so it’s not the normal incremental improvement we’ve seen in the past.
If you’re seeing things that aren’t working, please be sure to file bug reports and feature requests [link].

Element 3D requires an update for compatibility with CC 2015:

The only thing that’s natively accelerated by CUDA in After Effects is the ray-tracing renderer.

After my original post about the horrible live preview in CC2015 I went on vacation for most of July. When I got back the first thing I did was update all my Adobe apps and I must say that the After Effects live preview is MUCH better now! It is actually usable. I haven’t had a single buffering/preview problem since.
