Hello all, I wanted to share a small discovery related to this, a bit related
to a post I made a while back on reddit:
https://www.reddit.com/r/kde/comments/11detap/psa_on_nvidia_optimushybrid_laptops_using/

I've found that If I disable my integrated graphics from boot with the
following configuration under /etc/modprobe.d/10-blacklist-amdgpu.conf:

blacklist amdgpu

The performance on the external display is fine but my laptop screen doesn't
work, only the external monitor. 
However, if I add the module **after** I got into plasma with:

sudo modprobe -a amdgpu

I get video on both the external display and my laptop screen, and the
framedrops are gone! The CPU utilization is still high though.
