Ps: sorry for my bad english!

Sounds like the CPU to me, it's low frequency i mean, and the mobility card(should it be different in any way than the PC version)

And usually, most laptops are not for gaming.

farmdve, when you don't know what you're talking about you're better off not saying anything.

To the original post, try updating your graphics card driver.

cpu turbo freq is 2.8 GHz
gpu mobility 5850 is build on juniper gpu (5770)

crysis 2 demo has ran perfect

i have install lastest catalist driver
the screen is ok but avg fps is 15
(high,very high,extreme settings)
only this settings are in menu?

Honestly your problem is very strange. Your laptop specs are fine so no worry there, performance on the demo was also fine... I would try a re-install if I were in your position.

You should check your CPU frequency while in game, maybe it don't run at full speed. Also, try to enable the "high performance" mode in the power options, it will force your CPU to run at 2.8 Ghz.

thank you guys!

Win reinstall + catalist (nov/2010)
works much better (30-40 fps on high details /1600*900)
