IF your wallpaper is larger, the resource usage will naturally be higher, e.g. MPV's performance was at 3-5% CPU, the memory usage was at around 50. What is the performance impact of AutoWall? Most of the GIFs I recorded were pretty huge in size, so here's a short sample of the Mario wallpaper. The application also comes with the Weebp open-source wallpaper engine, which AutoWall uses along with the MPV video player in the background to display animated wallpapers. There is a reason why it is so big, the program ships with the MPV executable which is around 60MB and has a couple of DLLs required for the player. When extracted, the folder measures about 64MB in size. AutoWall is a portable software and comes in a 23.5MB archive.
