Source: Slashdot PaisteUser tips us to an Ars Technica report discussing how 28.8% of Vista's crashes over a period in 2007 were due to faulty NVIDIA drivers.

The information comes out of the 158 pages of Microsoft emails that were handed over at the request of a judge in the Vista-capable lawsuit. NVIDIA has already faced a class-action lawsuit over the drivers.

From Ars Technica:
"NVIDIA had significant problems when it came time to transition its shiny, new G80 architecture from Windows XP to Windows Vista. The company's first G80-compatible Vista driver ended up being delayed from December to the end of January, and even then was available only as a beta download. In this case, full compatibility and stability did not come quickly, and the Internet is scattered with reports detailing graphics driver issues when using G80 processors for the entirely of 2007. There was always a question, however, of whether or not the problems were really that bad, or if reporting bias was painting a more negative picture of the current situation than what was actually occurring."
