FCPX rendering trash after latest HS and Nvidia upgrade

[beachwood]

Since upgrading to HS I have not been able to get a clean render out of my FCPX. It comes out all blocky and pixelated. I'm running a NVIDIA GeForce GTX 760 2047 MB. Running the latest drivers. OS 10.13.4
Any suggestions would be greatly appreciated.

Ok I got it working today. Contrary to what I’ve been reading you do not want the internal intel graphics enabled. As soon as I disabled it, all was working again.
