Hello 2001hendrik
Since MSI GS60 Ghost is a high-end laptop, it meets all the recommended requirements to play Dayz Standalone.
Dayz Standalone's recommended system requirements are:
Intel Core i5-2300 (2.8 GHz)
Windows 7 x64
4 GB RAM
GeForce GTX 560 or Radeon HD 7790
DirectX 9
10 GB Hard Disk Space
It seems the game will run flawlessly and without any lagging on your new MSI GS60 Ghost laptop.
I hope this is helpful.
