Any way to make NVFBC to work?

[Balancer]

I'm trying to make the NVFBC to work with Steam Streaming to Steam Link and so far have had no luck. I do have the Geforce Experience installed and ticked the "Hardware Encoding" and "Prefer NVFBC" in the settings, but I only get d3d10 nv12+ NVENC H264 to show up in Steam Big Picture and In Game using my Steam Link.

Anyone successfully running NVFBC? Does it supposed to work while you are in Big Picture? Does it not work in some specific games? Is there something special I need to do to enable it? Maybe it's currently broken?

Any feedback would be appreciated! Thanks!

What GPU are you using in the host? OS? Driver version? etc... ;)

I'm not sure if it would say "Hardware Encoding: NVFBC" because, as I understand, NVFBC is a capture path where as NVENC is an encoding path.

Meaning, NVFBC copies the frame buffer from the GPU and NVENC encodes that frame buffer to be sent over to the client.

Anyways, that said, I've seen unofficial scripts about forcing NVFBC. For example, you can see

for his third-party solution. I'll try an update this post if I find any other information on the subject.

Looks like all of these problems are because of GeForce Experience 3.0

I just went back to 2.11 and NVFBC started working again! I wonder if nvidia somehow intentionally or unintentionally screwed up the encoding with the new version. Maybe it's a bug in the Steam client itself??

Anyway, for now, I recommend sticking with the 2.11 version of GeForce experience. My fps drops from 60 to 30 if the NVFBC is not used, so I need it to work.

UPDATE:

Looks like the issue is actually driver related. I rolled back to 375.76 and it works. I know it doesn't work with the latest 376.09. Hopefully NVIDIA is aware of the issue
