As promised, Nvidia has made new drivers available for Windows Vista, right on release day. Available for either 32bit-installs or 64-bit installs, the drivers are not yet WHQL and are considered Betas, but have been anticipated by many. If you're upgrading to Vista today, you may want to try them out, especially since they fix a number of issues with Vista support. The packages weigh in at nearly 42mb each for the US driver.
