Hi RushNuts,

Please provide more information of your TX1 BSP version, USB Webcam type, Video stream resolution, OpenCV (or OpenCV4Tegra) version and sample code you tested …etc as reference.

You could also try to fix the CPU/GPU/Mem to max freq to see if any help, User script attached.

Thanks

USB Webcamera - Canyon Web Camera CNE-CWC1 (USB 2.0);
Video stream resolution - 1600x1200 Mpx;
OpenCV4Tegra (from Jetpack v2.3);
CUDA 8.0 (from Jetpack v2.3);
I launching YOLO example and face detecting on OpenCV: fps ~10-15, but everytime have a delay 1 second.

Your script i can’t run, error showing: permission denied dbus

P.S. I have a PC configuration (OpenCV 2.4.13, CUDA 8.0 (also trying CUDA 7.5)) and on PC not delay.
