My games won't run properly

Hello guys,

I have an laptop Dell XPS : 6GB RAM(1066GHZ) ; Video Nvidia Geforge 555M and an i7 2.0Ghz (second generation).

The problem is that , when I run a game, in the menu all things are good. But when I enter in a mission, or start a campaign , it moves like a snail.

This happens ,since I have reinstalled my windows 7.

I have installed all drivers.(are all new)
I have installed directx.

Its an interesting problem, try running the game in "administrator" mode (solved a lot of random problems for me).

Can you download a CPU monitor to see if your CPU or GPU even react to stress from a game?

some games are very heavy for notebook graphics, so first of all make sure you are using latests nvidia optimus drivers, second, if the game is lagging, go lowering the graphics up to a level where you can play it at acceptable framerates.

Some games may be lagged even at very low graphics, so you can lower the resolution or search online for performance fixes (lowering graphics in the game config file and other)

if you are saying that the game is running at good frames but the controls response is very slow, try removing vertical sync before lowering graphics.
