Re: Didn't microsoft try that?
I sort of agree, but I believe it was just the other way around with NT. Moving the video stuff INTO the kernel ring to speed things up, for XP. I'm too lazy to look it up, but I'm pretty sure.
Oh, and apart from "speeding up" I'm sure it was something to do with compatibility with the Win95 driver stuff. That's really gonna introduce a lot of stability...
Having a video driver crash, taking down the entire system, is so Windows. (Which is why NT and 2000 are so un-Windows.)
