No...reinstalling Fusion didnt work...
Multiple times, updating drivers, running reg edit...no good
Had to do a full windows re-install
That obviously did the trick

I dont put the blame on drivers or win 10....as with a clean install all works fine.
As you can see, my issue was a little more serious, as I was missing the entire openCL menu across multiple fusion installs.
Hopefully you dont have to resort to such drastic measures....
