post details about your hardware and os
so what cpu, memory, storage, os do you have?
mobile components such as GeForce GT 550M graphic card are 1-2 generations behind their desktop equivalent models

so your video card likely does not meet the minimum requirements to run this game or if it does its very near the minimum requirements.
"Graphics:Nvidia GTX 460/ATI Radeon HD 5850 "
this also apply too all laptop components like cpu/gpu/memory/disk etc
so that video card is
GeForce GT 550M 794
and the minimum requirements is for
GeForce GTX 460 2666
so as you can see that video card is about 1/3 the minimum requirements
the same can be saif about your cpu/memory and storage...
laptops are just not gaming machines. best to get regular dirt cheap laptop with good battery life and then use the money you save to buy a good gaming desktop. in the end it costs less and runs games way better.
i have 2+yr old 6870 1gb and it runs great maxed out 1920x1200. so its possible to run this game with good framerate...

also look at this thread on tweaking the game and increasing performance
