I installed the Nvidia 340.52 driver and shortly thereafter upgraded to P3D 2.3 after a few minutes of running P3D, the screen goes black and I get a windows based message that the NVidia 340.52 Driver has crashed and windows is attempting to fix the problem. This has happened each time on three attempts. Is anyone having a similar problem? Could it be related to tesselization? My next option is to downgrade the video driver to the last good Nvidia driver.
