I hope i'm not jinxing myself, but since updating to the latest nVidia 591.44 driver, VP23 has not crashed once in 5 days. In the last 5 days I have been using VP23 extensively. I have completed 4 projects over the last 5 days without a lockup or a crash.
I will have to revert back to my previous driver at some point so I can use VP22 for certain projects in which I need to use the flicker control effect as that won't work with VP23. But for now, I'm impressed at how stable 23 has been.
