Topic: CPU load is higher than GPU's even with GPU acceleration ?

As title, my CPU load is always higher than GPU's even though I've enabled GPU acceleration.
For 1080p anime usually it's about 6~80% CPU and 40% GPU (motion vectors grid 24 px).
Sometimes even as extreme as 100% CPU and not even 20% GPU (motion vectors grid 6 px) and obviously 60FPS is not possible here.
Is this supposed to be normal ?
I've got i5-4690K clocked to 4.5ghz, GTX 970 with 353.06 driver, 12gb RAM.

A lot of the work still needs to be done by the CPU. Only parts of the work can be delegated to the GPU.

Ye that's how it always worked.

Give the rest of your GPU to madVR: he'll soak it all

How do I configure madvr to use the best of my GPU ? I'm using madvr according to the guides on internet but I don't know anything about it.
I mostly watch anime btw

NNEDI3 frame quadrupling and SuperRes will eat up your GTX 970.

You have to change the scaling algorithms, and create various profiles so that you select the right algorithms supported based on the resolution of the video you're playing. For example, 480p videos won't play with the same settings as 1080p videos.
