Vista RTM Is Buggier Than RC2?

I’ve had the RTM version of Windows Vista on my Toshiba Tecra M4 for about a week now. Strangely, I’m having issues with the machine that didn’t happen in RC2. I think it’s all traceable to the nVidia video driver, which was updated through Windows Update right after the install completed. I’m getting massive video corruption coming out of sleep mode (making the machine unusable), to the point where I now have to hibernate the machine instead of sleep.

I can’t exactly fault Microsoft for this, except that the driver came through Windows Update, so it should have been checked for issues like this before it was released. Hopefully this can be sorted out before the widespread release in January.
