Beta 3 - Now only uses 10% of GPU

I updated to Beta 3, now when I play back (or render), I'm getting 2FPS where I got 24 before. I brought up Activity Monitor's GPU monitor, and Resolve is only using 10% of my internal GPU, and 10% of my eGPU. But they "redline" at 10%, meaning their use is completely flat, as if maxed out... but at 10% of the capacity of the GPU.

I've already reinstalled, updated Mojave to current version, restarted many times, even used my copy of Resolve 15 that I've kept on the system, and even that now uses only 10% of both GPUs.

I've opened Premiere, and it uses 100%. The first time in history that Adobe Premiere is vastly outperforming Resolve

Any thoughts?

You haven’t described in detail the OS or GPU or GPU drivers and it’s likely to be an OS update that’s caused the issue and u need new GPU drivers.
