Bill Stubbs writes "NVIDIA has admitted to a killer bug in all GeForce 8800GTX/GTS cards, and will recall all affected cards and replace them. 'An NVIDIA engineer, who wishes to remain anonymous, has just clued us in on the whole deal. This engineer claims that while allegations of poor gaming performance are correct, the reason is not really poor drivers. Brace yourself for the truth: Right after the G80 was taped out, NVIDIA discovered a bug in the vertex shader that causes the GPU to generate slightly incorrect geometry transformation data. The difference was minimal enough to escape attention but it was significant enough to render a scene incorrectly.' The article also links to a secret website which will allow gamers to purchase Nvidia cards at cost."
I'd rather just believe that it's done by little elves running around.
