Apparently you have a laptop.
Usually the video adapter on a laptop is built into the main chipset on the mboard and it can't be upgraded, and that's the case for the g6s series.
If you wouldn't mind using an external monitor, see response 4 in this:
".... I'm asking if there is any kind of software which helps to make the game smoother, or if there is a way to make the video card better? "
Third party software - probably not, and you don't have a video card, you have onboard video - a video adapter built into the mboard. A CARD installs in a slot in the mboard and is removable - your computer doesn't have such a slot for that.
You can often improve the performance of a game by changing settings to lesser settings in the game itself. E.g. if you set it to run at a lower resolution in the game itself, it's more likely to perform better.
Other than that, the only things that might help are
- you can usually increase the amount of ram the onboard video uses in the bios Setup
- having more ram installed in the mboard.
If you have a 32 bit version of Windows 7, more than 4gb of ram cannot be used by the operating system, and if you install 4gb not all of it can be used - that varies from just under 3gb to a little more than 3gb. .
If you DO have a 32 bit version of Windows 7, you would probably be best off replacing one of your 1gb ram modules with a 2gb module for a total of 3gb.
Whether or not the game performance benefits from more ram than you already had installed varies.
"is it because of DirectX"
If you have a DirectX version installed that is supported by both the game and the video adapter, NO
Your video adapter supports using up to and including a certain DirectX version. If the game requires a higher DirectX version, you can install that higher DirectX version's software, but if the video adapter doesn't support that higher DirectX version, the fancy features that are supported ONLY by the higher version will automatically be substituted with a simpler version of the features .
