Having invested in Production Premium CS6 this year, I wanted to make the best of it, and upgraded both motherboard and graphics card to take advantage of the promised CUDA processing. Having done so, AE (Edit > Preferences > Preview) has consistently refused to recognise the card, and I am looking for advice on what I can try next.
For information, my PC system involves Windows 7 Home Premium 64-bit, an Asus P8Z68-V/PRO/GEN3 MoBo, 16GB RAM, and the new graphics card, a NVIDIA GeForce GTX 660 Ti (2GB DDR5). I have installed the latest Nvidia driver, 310.70, and the CUDA Toolkit v 5.0. It is possible to run the samples supplied with the CUDA Toolkit, and an application called CUDA-Z functions, both of which seem to suggest to a non-programmer like myself that the 1,344 CUDA processors on the card are working just fine.
It was suggested on another forum that I edit the file raytracer_supported_cards.txt which is in C:\Program Files\Adobe\Adobe After Effects CS6\Support Files to include the GTX 660. Other people have found this to work - i.e. that after doing so and resaving the file, AE recognises their card and its CUDA capability. I haven't.
I've run out of ideas. Does anyone please have either an explanation for the AE response, or a fix?
