Interestingly, Windows improved its stability problem through a combination of moving drivers into userspace and formal verification. Unlike in Linux, when your video driver crashes it usually just results in a momentarily blank screen instead of a core dump.
I would not say its true. Crashed gpu driver on linux will most likely leave you with locked out screen that does not accept any user input.
On the contrary, windows GPU(WDDM) drivers are restartable and can handle crashes even without restarting the user graphical apps. This've been so since at least windows 7.
