NVIDIA Display Drivers Causing Majority of Crashes in Windows Vista

nvidia_pie.jpgSurprised? You shouldn't be, considering NVIDIA drivers caused most of the crashes in Windows XP as well. It's just Vista's more graceful when it comes to handling said failures.

When Vista and DirectX 10 were announced all those years ago, it wasn't the graphics that had my giblets tingling. No, it was integration. Vista promised to treat your graphics card as part of the normal make-up of a PC, rather than an optional extra, by delivering GPU multi-tasking/scheduling and virtualised video memory. With these improvements, we got Aero Glass, Direct3D 10 and, of course, the Windows Display Driver Model (WDDM).Put simply (and I mean simply), Windows XP loads video drivers in kernel mode, which provides better performance to the detriment of stability, while Vista loads them in user mode, which has the opposite effect. Even Microsoft's own article on WDDM lists stability first under the driver model's benefits.

The point of switching kernel mode with user mode wasn't to reduce the number of video driver-related errors - it was to stop them from bringing the whole system down. Which, in my experience with the OS, it's done a decent job of doing.

But yeah - unsurprising numbers are unsurprising. What is amazing is that NVIDIA still hasn't done much to fix these issues. At least with AMD's cards you can reboot the GPU when it fails.

    Yeah I have a constant system crashes and reboots with my NVidia card!

    I had never had this problem before on vista but today after reading this article PC crashed due to display driver weird.

    Logan: Back when I was still a Windows man, and played World of Warcraft on an ATI card, the GPU crash recovery option seemed to introduce more instability than it solved.
    This was a number of years ago though on a ATI 9600XT, so the newer cards/drivers may be more reliable.
