Fusion too slow on W10

HI, I just installed Fusion 8.2.1 on my Razer Blade with GTX 1060 and it's too slow to work with. The second I load a frame it comes to a complete stall. Fusion is running onthe GTX, I have 16GB of RAM. Any clue on why it would stall? Resolve works just fine.

I saw that trashing the prefs could help. Where are the Fusion prefs on PC?

C:\Users\YOUR_USER_NAME\AppData\Roaming\Blackmagic Design\Fusion\Profiles\

SO it was just a compatibility issue with the NVIDIA drivers. Thanks for your help and time.
