Low fps on Alienware 15 R3 ( GTX 1070M )

Hello,

Alienware R3 2017 model here, re installed windows 10 and all drivers from scratch ( dell website)

I have Geforce drive 446.14 (latest)

Specs are basically i7 8 core, 8 GB ddr4 ram, GTX 1070M

I completed 2 benchmarks and everything seems to be working fine. (at least I thought so)

Installed BF5.

Now Geforce Experience ''optimized'' settings are on ULTRA!
I turn the game on, about 20 fps at, unplayable

Put everything on performance, I still get around 25-30 at max.

Disabled Integradted Intel graphic card,
turned off overlay and batter saver on Geforce Experience
Checked my Bios, up to date.

With all that, on lowest settings possible, I get 40 fps at max.

So it looks like hardware works but software doesnt or smthng like that.

Heaven benchmark results:
Render at dx11 1920 x 1080 4x AA Fullscreen
FPS: 62.2 (min 7 max 112)
Score 1568

What am I doing wrong? What should I do?

Any suggestion would be appreciated.

Thanks
