 Could you try with same encoding parameters, same '''preset'''?

Comment (by richardpl):

 One command uses preset slow and another one uses preset fast.
 I failed to reproduce using just overlay and movie filter.

 if you read my ticket, you will understand if it is an issue or not. In my
 opinion it is an issue (multiple ones).

 To record from webcam and microphone and overlay a resized logo, using
 complex_filter I achieve about 20fps (on a fast pc with less than 15% cpu
 load), using the same features but with -vf I get full realtime 30fps...
 I know this is normal because the complex filter has more options and it's
 more flexible, but IMHO this should not happen...

 Example:
 Record live feed from webcam and microphone, overlay a logo and save to
 flv..

 ffmpeg -f dshow -video_size qpal -rtbufsize 1G -copyts -framerate 30 -i
 video="BisonCam, NB Pro" -i "C:\Users\Zibri\Downloads\scdc.png"
 -filter_complex "[1]scale=80x60,[0]overlay=W-w-5:H-h-5" -f dshow -i
 audio="Microphone (Realtek High Definition Audio)"  -codec:v libx264
 -preset fast -b:v 500k -b:a 128k -minrate 500k -maxrate 500k -bufsize
 1500k -f flv test7.flv

 result:
