AE2014 does not recognize Quadro 4200 with Tesla K20. As I can see in this datasheet System requirements | After Effects, theese devices are not listed as capable. Is any chance to get it work? Should I install a special Nvidia driver or do something else?
Thank you in advance.
Do I understand correctly that I can add another video card to computer, which is in the compatibility list?
Yes, but there is very little reason to do that.
The only thing in After Effects that uses CUDA is the GPU acceleration of the ray-traced 3D renderer, and that feature is obsolete and being phased out. There are better ways to do 3D in After Effects, including using Cinema 4D (which is included with After Effects).
