And what exactly? Any card will/ should provide basic acceleration features for Fast Previews. The rest I would consider irrelevant unless you have some specific requirements...
Well the list from ADOBE shows only Adobe approved cards....are you saying any card should work regardless of the approved list shown. I spoke to ADOBE tech at support and he said "No only the ones on the list"...I sure hope you are correct...it opens a whole new world of choices.
Thanks Dave Kellogg
If you're using AE CC, there is no need to use the ray-traced renderer. It has now become obsolete with the arrival of faster-rendering, more powerful solution that comes FREE! Check out the details of CINEMA 4D integration with After Effects CC (12.0)
The card list on the Adobe page is for cards that are certified to accelerate rendering of the ray-traced renderer. Otherwise AE uses the GPU for very little. Read more on the GPU (CUDA, OpenGL) features in After Effects CS6 here. Now, some third-party effects (like Element 3d or Red Giant Universe) make use of the GPU, but their requirements are very different and they could use a much broader range of cards. If you plan to use any of them, you'd need to consult their requirements.
As Szalam an Mylenium say, there is only one obsolete feature that requires a card from that list.
Here's the relevant excerpt from the page that Szalam pointed to:
"IMPORTANT: A common misconception is that After Effects requires CUDA features of one of a specific set of Nvidia GPUs. That is not true. Only the GPU-accelerated ray-traced 3D renderer requires this. The other GPU features work on any GPU that meets certain basic requirements, including AMD and Intel GPUs. See below for details."
