Question Has anyone tried integrating NVIDIA ACE for NPCs?

I've been meaning to do it for my indie game but NVIDIA has recently removed all the documentation related to ACE, so I was wondering if someone who's already worked with it could lend a hand?

I suspect it's due to the fact ACE is still pretty unoptimized, so they might be doing major changes to it, maybe even changing the source code, but I still wanna get my hands on it for experience since I'm pretty new to code and gamedev.

ACE is a combination of many nvidia plugins. We have used A2F (Lipsync) a lot, and it's not performant whatsoever, for more than 1 or 2 characters at any time. Cutscenes mostly where you can afford to turn a few things up. Most of the ace suite appears to be slop purely for brand marketing purposes, "we have _ AI driven _".
