Above the line: the known issues each driver shipped with, either fixed in a later driver (or outside the driver, like a game patch) or still pending. Below the line: the bugs that driver fixed. Carried over: bugs listed under an earlier driver and fixed after this one, so this driver had them too. Bugs still pending aren't carried over. In the timeline, shaded areas mark GPU launch periods, from the launch driver of the first card to that of the last one, based on NVIDIA's release notes.
