![]() In video memory these images are decompressed which means they require significantly more memory than the original file size.īy default, when importing a new image into an existing wallpaper, Wallpaper Engine will suggest to use no compression ( "RGBA8888"). Graphics cards do not support rendering of common image formats like JPEG and PNG, so Wallpaper Engine has to convert them into a compatible format first. The padding also uses a bit of VRAM, so if you know you will not use any effects that go beyond the initial size of the layer, you can also set it to 0 (or if you need more padding, increase it as needed). This is to account for image effects that go beyond the object itself. ![]() We strongly recommend you make use of this functionality, especially on high-resolution wallpapers (4K UHD and larger), this can significantly reduce the VRAM usage:īy default, Wallpaper Engine also adds a padding to each cropped image layer. ![]() This will also automatically re-adjust the position of the layer to account for the space that was removed. Wallpaper Engine will automatically suggest that you crop imported image layers to a resolution that is as small as possible for that layer. See our Project Resolution Guide for more infos.Īdditionally, when using image layers, always make sure they are as small as needed. You should make sure the background image itself is only as big as you really need it to be, typically it should be exactly the size of a common screen resolution such as 1920x1080 (Full HD) or 3840x2160 (4K UHD). The first step in optimizing your project is to reduce the overall size of textures you import. The stats will then be displayed in the scene window in the Active texture memory row. You can check the currently required texture memory in the editor by clicking on View in the top menu row and then enabling the Show Stats option. Using less than 500 MB is also still acceptable but you should try and not exceed this limit for optimal performance. As a general guideline, we recommend using around 300 MB VRAM or less for great performance. If a wallpaper exceeds the graphics card memory, it can make the whole desktop unusable and sluggish on some systems. Some systems may have a limited amount of VRAM (graphics card memory). Reducing the memory required to display images will improve the performance and compatibility of wallpapers.
