My graphics automatically get set to - High (Laptop). I'm not sure if that's the auto setting for everyone or the game trying to recommend settings for me.

My system is as follows..
GPU: GeForce GTX 660
CPU: Intel Core i5-3570K @3.40GHz
Memory: 8GB
Resolution: 1920 x 1080 (60Hz)
OS: Windows 8

Can anyone suggest what settings I should run with?

Thanks
