Upgraded Graphics Card, GPU Utilisation used to be 70%+ now under 10%, slow render times

I recently upgraded my graphics card from a GTX 780ti to a GTX 1080, I'm using the latest version of Premiere Pro CC.

When I had the GTX 780ti my GPU utilisation during rendering was 70% or above and my CPU utilisation was often under 50% but since upgrading to the GTX 1080 my GPU utilisation maxes out at 10% during rendering and my CPU is maxed out at 99-100% at all times.

Not only this but my rendering times are slower than they were before the upgrade.

I've double checked the Cuda option is selected, I've done clean installs of the latest nvidia drivers as well, is there something else I need to change or select?

I would look to some other cause for the slow down.  Start with effects.

I haven't changed the effects I use, the type of videos I make, or anything other than the GPU.

I'm making identical content to what I was before the GPU upgrade.

It looks like Premiere Pro is just now underutilising my GPU, like I said, it used to take A LOT of work off the CPU to the point where my CPU was only under about 50% load but with the GTX 1080 my CPU maxes out and the GPU barely gets used at all (10%).

So is there another bottleneck?  What operating system are you using?  If Windows 8.1 or 10, the Resource Monitor will show you what is going on.

You can run my standardized hardware Premiere Pro BenchMark (PPBM) and watch the usage of the CPU and the GPU  intensive export those two tests (out of the four) always show 100% utilization of the device under test.  The scores from all four tests can also help find any weakness in your computer.

Hello!

Two theories:

1. New graphic card is much more powerful and simply does with 10% what previous did with 100%, thus choking the CPU... maybe CPU options need to be dialed in to something more appropriate... memory options?

2. New graphic card is not too well supported by Premiere... drivers? Old drivers?

Good luck in troubleshooting!
