Chapter 2 System Components per second. Furthermore, this was not when the packet size was minimized but when it was set to 9000. The rate shown in FrontRunner is the display rate. The camera itself is running at least twice as fast. The rate displayed on-screen when in live video is meaningless in terms of the application runtime performance. Dropped or Missing Packets Message Live video does however stress the PC more than the runtime.
If you have reduced the camera frame rate using packet size and inter-packet delay to the rate at which you absolutely must run and you get “Dropped Packets” messages when running in live video, then your PC is not capable of running the application and you should find a faster PC. The usual reason for this is the graphics adapter. Any onboard adapter that uses shared memory is going to have problems. The “Dropped Packets” message means that the NIC could not send data to the system memory in time because the memory or data bus was too busy. As mentioned above, an onboard or integrated graphics adapter using shared memory uses the bus extensively.
A dedicated graphics adapter is given the data it needs to display and handles all manipulations required within its own memory space, thus freeing the system memory bus. 2-36 Visionscape GigE Camera Guide
