it is hit and miss for me. For those that having it working reliably, what GPU and OS do you have.
I have an nVidia 660Ti / Win 10 64-Bit / Latest Driver (dec)
I have Windows 10 64 bit, Nvidia GTX 750, CPU is i5 3.2Ghz (PC itself is just a run of the mill Dell Inspiron)
It totally works for me. It goes in and out of 3D properly and plays perfectly. I can go to any 3D movie and follow with any 2D movie. The one and only problem I have seen is a 3D polarity problem with one movie. I haven't seen crashes.
I did have to dumb down my MadVR settings because otherwise I wouldn't have enough CPU I guess. I changed Chroma to something simple (Bicubic I think ...)
Also,.. it helped me to turn off Exclusive mode for video... that going into and out of exclusive mode didn't seem helpful.
I also ticked the box saying when playing 2D to disable 3D .. that was important or it wouldn't leave 3D mode.
finally...Jmone.. thank you for the script you made.. 2 days ago I was as happy as I could be with that... if this option never happened or doesn't pan out then what you did still totally works. (And has the advantage that I can do more with MadVR for 2D if I'm using SP for 3D.)
