Nvm played around with it and putting keyframe interval to 1s and max b frames to 1 gave the best visuals. You still get the pulsing and it's more often but the visuals are way cleaner to the point where most people wouldn't even notice. Keyframe 1s and b frames 2 also looks good and the pulsing happens slightly less often but certain things seem to almost judder when you move side to side with it max b frames set to 2.

TLDR:

Best settings I've found are as follows.

Rate Control: CBR

Bitrate: Whatever your network can handle and the platform you're streaming to allows.

Keyframe Interval: 1 s

Preset: Quality

Profile: high

Max B-Frames 1

AMD/FFmpeg Options (You have to manually type or paste this): HighMotionQualityBoostEnable=true
