The author notes that despite being WHQL certified, the GeForce 349.90 driver is a big mess and recommends rolling back to GeForce 349.65 if you're experiencing issues on Windows 10. That driver seems to be working great right now in combination with Windows 10 Preview Build 10041.
I'm not alone. A number of users on NVIDIA's GeForce Forums have reported experiencing crashes and BSODs. But the part about my experience that's worth noting is that unlike many of the users in the GeForce Forums thread I'm experiencing these crashes without ever firing up a DirectX PC game.
As far as I can tell from the forums posts there are some common threads among those like me who are suffering crashes:
They tend to have laptop graphics cards. I have a GeForce GT 650M (384 Kepler CUDA Cores, up to 900 MHz) [benchmarks]) Typically they have a high resolution display. I'm on a 2012 Apple, Inc. (AAPL) MacBook Pro w/ a WQXGA+ (Retina) display (2,880 x 1,440 pixels) The issues appear to be memory related. My GPU has to share a pool of 5 GB (out of 8 GB) of DDR3 with the CPU.
