What exact version of AE do you have (down to the last decimal)? What Operating System?
What do you mean by "can't good preview"? Please explain the symptoms.
What do you mean by "open GL mode"?
Please read this: FAQ: What information should I provide?
My AE version is CC 2015 13.5.1
My System is :
- Core i7 5960 (Overclocked)
- evga X99
- Gigabyte TITAN X 12GB (with latest driver 355.82)
- 32G RAM 3000
I have a big project - 95 layer with alfa channel and motion camera - in 1920*1080 res. and work with PNG sequence.
This system in slow for preview and render files ( 10sec. for each frame)
plz help me for best performance.
Are you using the ray-traced renderer to create 3d objects? If not, the GPU doesn't help anything in stock AE. GPU (CUDA, OpenGL) features in After Effects
Ten seconds per frame might not be bad. I've done some animations where it was over a minute per frame! To find out if it's a bug with CC 2015, try opening that same project in CC 2014: How to Find and Install Previous Version of Adobe Apps in CC 2015
