Hello guys.
Got my new ASUS K55V, Intel Core I5, 2,60GHz and Geforce 610M 2GB.

In LFS I got some big fps problems, when I start the game, the fps is 130 and after 1 minute it drops to 30 fps and don't want to return to normal fps.

What can I do? Thanks, JEP.

Similar specs to my new laptop (also Asus),never had problems and have 60-80 fps with almost all maxed out (not max AA) on FullHD res. First what I got in mind - check cooling and chech power/performance management. Or plug in mains power adapter,it won't run full performance on battery. Just guessing,no PC expert/tech here.

Thanks but every thing is ok about the temperature, anyone alse?

as eclipsed say, almost all notebooks of today have a power saving feature that you can disable from control panel "Power managent"

Also make sure you are using the lastest drivers for your video card

Updated the driver, canceled the power saving and nothing :/
Very bad fps, what can I do?

Is it doing only in LFS? Have you checked other games / videos / films / 1080p?
