Meanwhile, according to Wikipedia, the minimum system requirements of Red Faction: Armageddon are:

CPU: Intel Core 2.93 GHz or AMD Athlon(TM) 64 9400+
RAM: 2 GB
Video cards: 1024MB Geforce GTS 250 or Radeon R600

No doubt, Red Faction: Armageddon is a game that is very heavy, in theory, the Pentium 4 processor can not run this game. Even, the GeForce 8800 or 9800 series (or even the GTS 250) which usually can play any game with high settings, will only be able to run Red Faction: Armageddon with minimum to medium settings.

And also, this information should only be used as a guideline only, because in reality there may be significant differences.

Dirt 3 recommended system requirements:

OS: Windows Vista or Windows 7
Processor: AMD Phenom II or Intel Core i7
Memory: 3 GB
Hard Disk Space: 15 GB
Video Card: AMD Radeon HD 6000 Series

According to several sources of information, DiRT 3 is using the similar engine as Operation Flashpoint: Red River and F1 2011. No doubt, the graphics quality will be outstanding. According to the plan, this fantastic racing game will be released on 24 May 2011, and players can feel the cockpit camera view.

That’s all information that I got through forum.kalypsomedia.com, the official forum of Kalypso Media.

* Processor: 3.0 GHz P4 or Intel Core 2 Duo 2GHz or equivalent or faster
* Memory: 2 GB RAM
* VGA: 256 MB Video Card with support for Shader Model 3.0
* The latest version of DirectX 9.0c
* OS: Windows XP Service Pack 3 / Windows Vista Service Pack 2 / WINDOWS 7
* 10 GB of hard drive space
* Broadband internet connection

But, there is no clear information about the recommended system requirements, at least until recently. The information above are the minimum requirements. Our guess, likely to be very difficult for you to run this game if the specifications of your PC / laptop is the same as min requirements above, because most of the EA Games usually run very slow on a PC with lower specifications. Therefore, it is better to upgrade or use a PC with a slightly higher specs, like for example:

Processor: Core 2 Duo 2 GHz (same)
RAM: 4 GB
Video card: GeForce GTS 250 / GeForce 9800 GT (min)
OS: XP SP3

Maybe, if your PC specs as above, would be more comfortable. Meanwhile, according to game-debate.com, recommended system requirements from Darkspore are as follows:

CPU: Core 2 Duo E6400 2.13GHz / Athlon 64 X2 Dual Core 5000+
RAM: 2 GB
Video cards: GeForce GT 330 / Radeon X850 Series

Hopefully you will be able to play this game smoothly. And should, system requirements above are only used as a guideline only, because in fact you may will find the difference.

Functionality of a Device Driver

The basic functionality of Windows 7 device driver is to develop a good communication link between Windows and the device in the computer system. The driver helps the device to understand the instructions given by Windows and vice versa.

A lot of hardware devices present in a computer system needs a series of different drivers to work. A number of device drivers for devices like network cards and graphics card are installed automatically when Windows 7 is installed in a system. However there are still a lot of devices for which you need to install a driver manually.

Older Devices and Device Drivers

If you have an outdated web camera and want to install its driver for Windows 7 then you need to search for its driver on the official website of Windows 7. However if the camera is old enough there are huge chances that you won’t be able to find it on the official site.

Now What Needs to Be Done?

Plug in your camera and for sure Windows 7 won’t be able to run it properly. You can check this by opening up the device manager by going to the Control Panel, System, Hardware, and finally the Device Manager. Here you will see an exclamatory mark of yellow color beside your web camera that means your computer is unable to locate the driver for your device.

Now what you can do it update the drivers with the help of Windows update present in Windows 7.

* Click on the Start button, then go to All Programs and then select Windows Update. This will open the Microsoft Windows Update site.

* Now check the latest updates for your computer on that website and there are huge chances that you will find some driver for your camera there.

* Now follow the instructions given step by step to update the driver automatically.

* Open the Device Manager to check if the new diver icon is present there. If it is, then the computer has successfully installed the driver for your web camera.

* You can also check if the camera is functioning properly by opening up some video recording software to see if it is functioning properly.

* You can also update other drivers for older devices

However, if you are still not able to update the driver by Windows Update you can look up on different other websites which provides such drivers. You can look up on any search engine by entering your device model number along with the manufacturer’s name for Windows 7 and you will get the whole driver download process for Windows 7. This website can help you to find your drivers software http://www.bravofiles.com/.

Supported chipsets: ATI HD 3 series or greater; NVIDIA GeForce 8 series or higher. Laptop versions of these chipsets might work but are not supported. Updates to your video and sound card drivers possibly required.

Until now, there is no information about the recommended system requirements from Need for Speed: Shift 2 Unleashed, but, at least the official minimum system requirements above can provide a complete information to you.

For recommended system requirements, until now, there is still no information. Maybe, if your PC specifications at least as above, I am sure you will be able to play Portal 2. If you want to play with high resolution and high settings, it is advisable to use a higher video cards, the GeForce GTS 250 or GeForce 9800 GT seems to be the right choice.

Recommended hardware (system) requirements:
Windows Vista or Windows 7
Quad Core 2 GHz+ CPU
2 GB RAM
GeForce 260 or ATI Radeon 4850
10 GB of free hard drive space

Yes, the GeForce 260 or ATI Radeon 4850 video card is recommended to play Homefront smoothly at high resolutions. But, if you just want to play it with medium settings (and not very high resolution, for example 1024 x 768) I think the GeForce GTS 250 or GeForce 9800 GT is enough.

Recommended hardware requirements:
OS: Windows Vista (SP2) or Windows 7
Processor: Quad Core 2.0 GHz
Memory: 2 GB
Video Card: DirectX 9.0c compatible, 512 MB of VRAM (GeForce GTX 260, or ATI Radeon 4870)

After knowing the system requirements, now is a good time to buy (pre-order) Bulletstorm from EA Store and get Shank for free. However, this game is fun, you’ll get new and different experience when playing this FPS game (character control, darkly humorous storyline, complex Skillshot-based combat and weapons system, etc).

Recommended system requirements for Rift:
CPU: Core 2 Duo 2.2 GHz or better
Memory : 4 GB
VGA / video card : Nvidia GTS 250 or better, Nvidia GTX 200M series or better

If you have a GeForce GTS 250 I am sure you will be able to play Rift smoothly without lag. Most of the existing MMORPG games do not require “extreme” specs, it is important you use fast and stable internet connection.
