dx9 is compatable with intel(R)82945g and mostly any motherboard. the compatability of directx depends on the os and the graphics card in your system.

If your computer uses the Intel® integrated graphics controller and has an HDMI port, you can download the latest graphics driver for your Intel chipset; installing the graphics driver will also install the HDMI audio driver. this is the direct link ti Intel motherboard drivers: http://www.intel.com/support/chipsets/sb/CS-009244.htm

When your computer loads, after you power it on, it gives you an option to go into the CMOS. You can disable integrated periferals there. If you don't know how, check your system documentation

Driver

I highly doubt that the driver will do much at all to the shaders. You probably need a new graphics card, to run the more mainstream games.

from WIKI:

A video card, also referred to as a graphics accelerator card, display adapter, graphics card, and numerous other terms, is an item of personal computer hardware whose function is to generate and output images to a display. It operates on similar principles as a sound card or other peripheral devices.
The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard, as opposed to a graphics controller integrated into the motherboard chipset. An integrated graphics controller may be referred to as an "integrated graphics processor" (IGP).

next time do some research. GOOGLE it.
