I have an ASUS A43SD laptop with a built-in NVIDIA 610m graphics card. I recently switched to Windows 7 64-bit and in the process did away with the NVIDIA driver I had installed. As far as I can tell, the computer has no idea it even contains a dedicated graphics card now. The Intel Graphics and Media control panel, which is installed, seems to handle DirectX rendering and offers other 3D settings, and although I haven't tried any 3D-intensive stuff yet, I haven't noticed anything out of the ordinary about display or performance.
So, what exactly is my graphics card doing?
Is my computer using the graphics card at the moment? Should I still try and download the NVIDIA driver to take advantage of the card? Is there anything I should know about priority or conflicts among these control panels/drivers?
