I installed this application for the first time today and it just doesn't work. I opened the settings and selected each Media Foundation, DirectShow EVR, and DirectShow VMR-9 with the Quality setting set to best and had NO success. The application loads the selected wallpaper media (Desktop Mars by Stardock Design) and applies it to all Monitors. This works for about 4-5 seconds before switching to the Windows 10 wallpaper desktop background previously set by Windows.
I am running Win10Pro (v1909) on an Intel i9-9900K w/64 GB DDR4-RAM, ASUS Strix ROG Ti 2080 GTX. There shouldn't be a performance issue. I am running the latest Nvidia video drivers (442.19).
Nice program if it worked
