Late last week, nVidia released the 32bit and 64bit driver package for Windows Vista. If you happen to already be using Vista or want to be ready for when it goes retail, you can download both versions
at nVidia's site
. Both packages are WHQL certified and weigh in at around a 50MB download. If you are using a pre-release version of Vista that has a build version below 6000, the drivers may not work for you.
The updates in this driver package include protected-content playback support, whether it be Microsoft's custom DRM or Blu-ray DRM, updates to how the control panel is accessed and a few other minor fixes.
