Great, thanks for all the clarifications, two last things though:
1 - You claim 516.93 is the last working driver, but you then put a link for 531.68 and say that you're back to 531.68. So what's the real last working version, 516 or 531?
2 - Does nVidia really have support for these kind of things? You said that you've have bug reports for years, which actually answer my question a bit, but I mean, does nVidia gives support for non-official uses of the card/driver? Or using the driver/API the way the app does it is included in the list of functions of the official API? In that case, if they have official support for their API, I guess they
should give support for this kind of things... I'm sorry, it just sounded a bit weird to me to open a bug report to nVidia for an app that has nothing to do with them, and although it uses their API, it is used for video editing in a way that nVidia does not provide officially.
Again, I'm sorry, english is not my native language, I hope my doubt is clear
