Hi Mark,

I don't think so, because VTK has to check every individual
graphics card. They store their version information at
different locations in the registry, as far as I know.

You could only check the OpenGL version, but it does not
say anything about the graphics card driver.

If you always use the same card, your application might 
read the registry string an compare it.
