Guys, I just bought new laptop with this specs

core i7
6 gigas ddr3 1333mhz
geforce gt 540m Cuda

For more detailed info about this specs you can check this website --> http://www.fnac.pt/Asus-K53SV-SX285V-Dark-Bro...6&Fr=0

Well the main problem is that i bought it and I can´t get stable fps ( 125 fps). Also in maps like vertical vengeance I reach 80 fps...

Strange stuff cause I play other games or tried at least for example Fifa 2012 demo with high graphics, on my hdmi tv and it works fine...

Please someone help? I´m really needing a help here =)

Thanks a lot in advance and sorry to bother you up. If you need screens of my fps or anything just say
