Question / Help Stream lag when locally recording/streaming at 30 fps but not at 60

[BHPirkle]

Hi everyone, so I have an Elgato Video Capture (non HD) and I capture a N64 via composite. When I stream at 30fps, Super Mario 64 seems to lag on higher motion parts of the game (such as the intro when Lakitu is flying around. Lag doesn't really make a whole lot of sense because I have a decent box and my internet speeds are sufficient. The lag appears on stream as while as in my local recordings. However, when I go from 30 fps to 60 fps the lag goes away. My thoughts were is that 30 fps is too slow for capturing, but I was always under the impression N64 games were 30 fps, and other streamers i've talked to shoot at 30. What could be causing this issue?

Specs:

Bitrate : 2000
Res: 540p
Frame: 30/60

Cpu:

Intel 4690k
Integrated Graphics

Try posting log files from at least five minute recordings, one from 30fps, the other from 60fps, that demonstrate this happening.
