P.S. Tonight I will repeat the same test with my Desktop PC to see the difference with my laptop.

My PC config is :

Windows 10 64Bit Pro Eng
i7-7700K 4.5 Ghz (running at a real and constant 4.45 Ghz)
32 Gb DDR4 at 3000 Mhz
SDD NVME M2 Samsung Evo 500 GB
and...Custom Gtx 1080 Ti (11 TFLOPS in FP32 and 11 GB GDDR5X RAM)
