I am a college student and I bought a new pc with nividia drivers optimus graphic card.but when I opened the control panel it says you can download drivers and the software I cant relly understand that why the owner need to download additional drivers for the graphic card,should not they be pre- installed ?and why these drivers come out periodically like updates forcing me to come back and download in the future? And what do these drivers/software do for the graphics card? Pls help iam confused with all this stuff.
