You are using what's referred to as an "Integrated Graphics Card" (the 'video card' is built into the motherboard). These are WORTHLESS for playing games. They were not intended for 3D gaming performance, but were intended for smooth desktop applications (email, internet, accounting software, office programs, etc).
If you wish to play video games then you should purchase and install a "Discrete Graphics Card". This essentially means you install a part into your computer that does all the 3D rendering so your processor (CPU) doesn't have to do so.
