Ok quick thoughts... If you're doing 4k video already... a lot of video features don't work.
Frame Gen: Only up to 60fps if you're not delivering that to the system now and are at 30 or whatever frame gen might help. Otherwise it's useless.
Video noise removal I didn't tinker with.
Sound profiles for microphone... already have them on my headset... Broadcast's just kinda meh. (Great if you don't have this already!)
Noise removal already have on headset. Again great if you don't have this already!
Eye focus on camera... very VERY uncanny valley at least when testing with a few others. Neat if you're one of 50 in a call with a manager that looks for people that seem distracted.
Auto framing, can be very handy if you don't have that function already.
Really in short the Broadcast app can really make mid to lower end headsets more feature complete for a lot of neat things (and your webcam's too Looking at you laptop based web cams!) at the cost of GPU cycles.
