I looked at a bunch of answers to previous posts with this same problem and could not find a clear answer. It really started failing to launch a lot when I installed the second video card. I have gotten the new drivers for the video cards.
Faulty video card?
here is my computer info:
ADOBE AE CS6 (version 184.108.40.206)
Intel i7 - 960
Windows 7 (Ultimate/64-bit)
24 GB RAM
Device: GeForce GTX 660 Ti/PCIe/SSE2
Fast Draft: Available
Texture Memory: 600.00 MB
Vendor: NVIDIA Corporation
Total Memory: 1.95 GB
Shader Model: 4.0 or later
Driver Version: 5.5
Devices: 2 (GeForce GTX 660 Ti, GeForce GTX 660 Ti)
Current Usable Memory: 1.77 GB (at application launch)

Those cards are not on the list of cards that After Effects will use for GPU acceleration of the ray-traced 3D renderer:
Did you make a change to a file to try to force these cards to be used? If so, that's an unsupported configuration.
