PIcked up a new 770GTX and installed the latest drivers from Nvidia which are 320.18. Unfortunately Adobe apps don't recognize the GPU. The only thing I can think of is the latest drivers also includes an updated CUDA 5.5.1 driver. My older 570GTX is running drivers w/CUDA 5.01 or something. Is there a document anywhere which states the CUDA driver requirements? I was suprised that CC didn't come up to date.
The driver requirements haven't changed:
CUDA 4.0.50 or later
But your card isn't one that After Effects will use for GPU acceleration of the ray-traced 3D renderer.
