animation very choppy,please help

hi guys,hows it goin'?

i made the jump from sony vegas to after effects about a week ago and it blew my mind.AF is awesome,i love it

however,im having some problems with animation.more specifically...its not smooth.it feels very choppy.and im not talking about the PERCEIVED smoothness of the animation,im talking about actual FPS.

im running the project in 60fps,and im hitting F9 on all keyframes for easing etc.however,its still choppy.its not that real buttery seamless smoothness.

lets say im moving a logo from point A to point B...it feels like there should be extra frames drawn in between each advancement of the motion.

heres a crude mock up i made to explain (picture the logo traveling diagonally and each still represents one frame)

they are screenshots of two instances of AF taken one frame apart and overlayed (they are not perfectly aligned).im just using them to illustrate my point.

basically i feel like there should  be an intermediary instance of the logo positioned between the red lines (to fill the void and add to the smoothness)

im uploading a video too so you can tell me if something is wrong or if this is the best i can hope for far as smoothness goes(but its taking some time.the file size is almost 3GB for a 7 second video...that also seems a bit odd)

anyway,any help would be really appreciated.i want everything to be super smooth .i hate choppiness
