OpenGL 2.0 Video Card or driver update needed. What are they?

I've installed a graphic arts plugin/Fractal application to my Dimension E310 and attempts to use this application tells me that I need to update my video card or video card driver to one that supports OpenGL 2.0. The video card that I use with my Photoshop Cs3 application is an Intel(R) 82915G/GV/910GL Express Chipset. It seems that the new software applications installed to work in conjunction with my Photoshop Cs3 program briefly worked one time after I reinstalled some video drivers upon my initial attempt to know what I was doing.  But that was just a test to see if they would open up.

I am not that familiar with the graphic cards that contain OpenGL 2.0 technology. I need a fast course in what it is so I will know what I will have to do to get my applications(plugins) inside Photoshop to function as they're suppose to do without my wondering if they will when I'm ready for them.
