That is.... AWESOME! Just what I searched for! You know what? A year or so ago I made a video complaining that the Ultimate Recorder don't exist. But I think that you might just have made it, as the first ever none-capturecard required program to include all the most wanted features a YouTube-Gamer needs.
For other people trying this feature, the test showed the following:
I noticed that the cam is locked to 30 FPS, might be the webcam hardware though.
Also noticed that Bandicam starts recording the webcam 1-2 seconds before it records gameplay so cut that out and it'll be synched.
Thanks again Bandicam, you just made it to No 1.
