5. Ignore Audio Mode
In normal mode ActionCam2PC tries synchronize video and audio. This process increases latency sometimes.
As option you can say - "I don't need audio" from action camera.

Also in this mode you can setup buffer size. It will drops frames when buffer is full.
The app uses buffer to stabilize frames. See image below.

Big buffer means "no drops", little buffer may be means "we allows drops".
