Hello, world of After Effects!
A French user reported ( http://forums.adobe.com/thread/1338571?tstart=0 ) slower previews and renders when he went from an ATI FirePro 3D V3800 to a Quadro K4000 with the 331 drivers on his HP Z400 under Cs5.5.
Is it normal? Should he optimize something?
After Effects CS5.5 used the GPU for almost nothing, so there should be no difference in rendering, either for previews or final renders.
The only exception is if he is using the OpenGL preview renderer, which no one should ever do for anything but the roughest of previews. Keep in mind that we threw this renderer in the garbage when we moved to After Effects CS6; anyone using it in After Effects CS5.5 should be told to stop.
Thank you, Todd!
