Asus K53TA. Quad Core 1.4 GHz CPU, 4GB Ram, Radeon HD 6720G if my memory serves me correctly.
No offence but it's your fault for buying the game thinking it could run on that. I want to say the 4GB RAM is really fucking you but your CPU and GPU are also pretty bad.
At least it'll motivate you to get a nice gaming desktop. As someone who recently switched from a "gaming laptop" to a actual gaming PC I'd never buy another laptop again.
