In AE CC preferences>previews>gpu information under OpenGL it reads:
Device: NVIDIA GeForce GTX 780M OpenGL Engine
Version: 2.1 NVIDIA-8.24.9 310.40.25f01
Total Memory: 2.00 GB
My questions is why does it read 2 GB when my graphics card is 4 GB? Is AE not using the full power of my graphics card then?
I did further research and found that AE for both OpenGL and CUDA cards, it only supports up to 2 GB for each card. As stated here, if you scroll down and watch the video: After Effects Help | GPU (CUDA, OpenGL) features | CC, CS6
