So many people wrote about this that I have taken it for my own. Tough. nVidia has been sued yet again, this time by 3dfx. 3dfx is alleging that nVidia is using 3dfx's multi-textured in the new Riva TNT chip. nVidia has already been sued by S3 for similar reasons. nVidia has been getting bigger lately, and were hoping to have an IPO soon, so this suit comes at a bad time.
