X-Plane 10 is very unforgiving of Laptop Hardware (in most cases unless you have a Hi-End $2,500+ Desktop in a Laptop). And although your Laptop is powerful for a Laptop - you can see that it isn't optimum for X-Plane10.
X-Plane 10 runs best with Full Strength Full Size Hardware:
Core i7 4790K (Haswell) on Z97 Chipset
Core i7 6700K (Skylake) on Z170 Chipset
Nvidia GeForce GTX 970, 980, 980Ti, TitanX
Your Laptop would run X-Plane 9 much better and as far as flying goes - it's still a Great Flight Sim
