Recently, I have been using the nDisplay module in UE5.1 to serve as the display for my own simulator. In terms of signal transmission, I configured a UDP transmission module to implement the movement of character coordinates (X/Y/Z), and used the nDisplaySyncParent component from the official documentation to synchronize changes across child nodes. However, I noticed a delay of approximately 3 seconds from signal input to the start of frame movement. After checking the source code and modifying the thread priority of nDisplay, the delay was reduced to 1 second, which is still unacceptable for a simulator. I am now completely stuck and would appreciate any help on how to address this issue.
