Did you use DDU to remove old Nvidia drivers before installing the newest Drivers?

Also only dx11 works with sli currently in bf1. Choose that for now.. sli will get better scalling with game updates.

120FPS sounds about right, keep in mind kitguru are benchmarking singleplayer campaign which will have significantly higher FPS than multiplayer, so if youre comparing your multiplayer numbers to their single player numbers there will be a big difference

I'm getting in the 140+ fps I'm multi-player using classified 1080s at 2190mhz and my 6700k is overclocked to 4800mhz. 16gb ram at 3600 15.15.15. And that's on 64 player servers. At 2560x1440 at 165hz.

Butter smooth with everything maxed out in win10 pro 64 build 1607 using the dx11 mode.

Of using a g-sync 144hz monitor and getting over 144fps then you'll want to cap the frame rate at 143fps using evga's precision x to keep the game runing stutter free.

Cheers all , reverted back to DX11 and capped fps to 144 smooth as out now but DX12 does look better..
