Latency variation in camera stream displayed on an LCD

I am displaying a camera stream at 30 fps using a qt based application. I am using eglfs as platform in multi-user mode(No desktop) to run application. I getting consistent frame rate from the camera in Network. But I am seeing glass to glass latency variation of approx 50ms. Is there a way to reduce the variation and keep the latency constant ? I have used jetson clock to maximize the performance and usage of eglfs also lift rendering load from CPU.

Please run VIC at max clock for a try:

If the issue is still present, please execute sudo tegrastats to get system status and check possible bottleneck.
