That's great news. Two of my higher-end PC's have NVIDIA cards in them for gaming and I was constantly getting the KERNEL_AUTO_BOOST blue screen of death because of the driver issues.
Got so bad I had to go out and buy a low end video card as a temporary fix. The drivers with that $39 card worked fine. The drivers for my GTX 970's would just randomly cause the KERNEL_AUTO_BOOST blue screen and memory dump whenever it felt like it.
Personally I'm holding off on the upgrade to Windows 10 until that driver issue is fixed on the machines I have with NVIDIA cards. The rest can get updated anytime.
I just rolled mine back to the previous drivers and have refused the updates until they fix it...
Good to know they have it under control..
