Doom9's Forum - View Single Post - increasing b-frame is good or not?

Yes, so I fully understand that it is Adaptive, and x264 does seems to use more b frames after the max is set to 16, but the overall bitrate & PSNR is also decrease a bit.
So the main target that b-frame is introduced to video codecs is to increase the bitrate efficiency or increase the quality? I'm a bit confused...
