I don't think anyone else is having this problem so it's likely not an issue with this wallpaper. If you want you can make a post in the support section.

Love Wattson, and cyberpunk is one of my favorite. although as much as i like it, i almost don't want to use it because the frame rate is so bad, idk why. All my other wallpapers from wallpaper engine play just fine, they don't look laggy, just this Wattson wallpaper is laggy.
