how do i know what kind of driver i have?

How do i firgure out what kind of driver im currently using?

If using windows, go to the c:\windows\system folder or if xp, c:\windows\system32. In bottom of window make sure show "all" files is selected then, highlight and R click on opengl.dll or opengl32.dll (depends on os) then click "properties" It will tell in there what version # it is. Another file that goes with it is glu.dll or glu32.dll.
