It runs IntelHD graphics 4000 series which in this case is APU "Accelerated Processing Unit" and your laptop APU will be struggling with this game, I don't want you to go to BIOS and tweak up video shared memory with no experience especially, the next is, locate in system tray IntelHD graphics panel/ right click on it/ Properties or settings.
There you should find a power balance and set it to performance/high performance because at ballanced mode the APU is 40% usable.
I have a Mac and I don't know if this is just me being (not so) clever but, its coming up with an error message when I try to open it saying it 'quit unexpectedly'.
Will it work once the servers are up?
You need to seek for help, I'm sorry, but I have almost no experience with Mac, but the game crashes on your Mac PC
First check if you GPU drivers are up to date, I don't recommend to overclock the GPU if it is weak, if it doesn't help try to download different bit version of the game, or if it's still doesn't help, then you need to change graphics settings via "nVidia control panel" or "ATI AMD catalyst panel".
I'm going to be completely honest here. I have no idea how to check my GPU drivers. I have no idea what "nVidia control panel" or "ATI AMD catalyst panel" are or how to access them. I am not very tech savvy at all.
First, do you have Desktop computer or Notebook?
I have a Toshiba Satellite laptop
That explains a lot, well if you can give me exact model name, I could try to help you how I can.
Toshiba Satellite C855-S5343
I also use Windows 8, if that helps any
Windows 8 is more friendly than it's previous brother Windows 7
