Adobe after effects cuda?

wondering if the cuda for after effects cs6 is only for ray tracing? 
I really want to use my new gtx 770 to render videos instead of my core i7-3770k..
Im running windows 8.1 64-bit.

I have already eddited the txt file that lists usable GPU's. now it allows me to set ray trace to gpu but when i render it seems my cpu is the only thing that revs up and my gpu (using msi afterburner) stays around 0-3%. I kept watching logan talk about how he loves adobe programs along side his nvidia graphics cards yet im having issues and cant wrap my head around why this doesnt just work out of the box.

Can anyone help me?  my graphics drivers are the latest 331.65
