Does the new Media Encoder CC automatically use GPU and CUDA encoding when available? I tried to export H.264 from After Effects CC, but I found that you have to send it to AME for this, and then I'm not 100% sure if the GPU is used? I see that the GPU is only used about 1-2% when encoding.
I have a GTX 570 card installed, so I know that GPU is available, since it's working fine in Premiere Pro CC.
