When Visualizer is running the system works very slowly similar when it is under stress. CPU is loaded by Visualizer on 20% without any visible actions, no content on the video wall as well.
Video wall 6x4 with full hd screens. Datapath VSN controller with two Xeon CPUs, ImageDP4 cards and one Datapath capture card. No side software installed and running.
Set Visualizer settings as on the screenshot.
