Horrible support here on purpose? #Flex

Hey I wondered, if the non-existing support - e.g. for the Flex engine - in this forum is on purpose?

Especially regarding NVidia Flex it is almost impossible to develop anything given the spare documentation and extensive demo files.

Since there are about zero replies from the NVidia Team regarding this topic in general, I wonder if I somehow have to purchase a professional license to get any feedback?

Well, PhysX (and corresponding products) support on public forums was always very shallow, even since Ageia times (2006-2007). Try to contact them directly, for example trough physxlicensing@nvidia.com
And yes, they indeed have paid support option (ticked based).
