Q: I've upgraded to 295.xx/296.xx drivers and now my Cuda tasks are erroring and my RAC is dropping.

A: There is a Sleeping Monitor Bug with the 295.51, 295.73 and 296.10 drivers, once a DVI or HDMI port connected Monitor goes to sleep, the Cuda device becomes unavailable,
the next time a cuda workunit starts, the Stock Cuda app will jump into CPU fallback mode and run very very slow and eventually error out, while the latest Lunatics Cuda app
will attempt to start the workunit a number of times before erroring out, the solution is to upgrade to 301.xx or later drivers, or downgrade to 290.53 or earlier drivers.
