Furthermore, several causes could be causing the Wallpaper Engine to slow down the computer. Among them are:

  • System requirements concerns: When your PC isn’t powerful enough or doesn’t satisfy the app’s needs, it can cause problems.
  • Problems with graphics cards: Because Wallpaper Engine uses graphics resources on your computer, problems with your graphics cards will have an immediate impact. As a result, an outdated or malfunctioning graphics card can cause Wallpaper Engine to crash or lag on your PC.
  • Wallpaper Engine app is out of date: The software is continually updated to improve its speed and solve flaws that affected its previous version. As a result, not having these updates installed may cause problems with the app.

These are some of the causes of Wallpaper Engine lag. Regardless, by troubleshooting your PC, you can get the software to operate again.

Why is Wallpaper Engine so sluggish or Slow?

This could be due to your hardware not being powerful enough to properly display the specific video. Video wallpaper is not the same as a conventional video player because it must also have icons and may span many screens. It also uses your GPU’s video decoder by default to keep CPU utilization to a minimum.

Hooks in the background recording

It could also come from any driver feature that allows you to record apps like ReLive, Shadow Play/Nvidia Share, or Windows GameDVR. Disable them to test whether it makes a difference, then remove Wallpaper Engine from the list. Also, ensure that no other recording/overlay programs are loading into Wallpaper Engine and slowing down rendering.

You can use our scan tool to see if any apps that are known to cause these types of problems are installed. Remember that our scan tool cannot dependably uncover the main cause of this problem – it may fail to detect any problem or may report an application that is unrelated to your problems.

GPU Scaling / Dynamic Super Resolution (DSR)

Driver-level hacks such as GPU Scaling/DSR may also create issues; try disabling them and, if necessary, disabling them specifically for the Wallpaper Engine.

In systems with multiple GPUs/screens, dwm.exe performs poorly

If you enable the integrated GPU in the BIOS of your desktop PC while having a separate graphics card installed, you may have poor DWM.exe performance and significant CPU utilization. If at all feasible, disable your integrated GPU.

It is critical to connect all of your monitors to your dedicated graphics card. Using both GPUs at the same time will disrupt desktop window manager hardware acceleration. 

Without Nvidia Optimus or equivalent technology, Windows will be compelled to copy the wallpaper image from one GPU to the other, which will be a slow operation. 

In fact, any shared activity between both GPUs will suffer from this, as would moving a game window directly between both monitors.

This issue does not affect gear designed for multi-GPU configurations, such as laptops with Nvidia Optimus or true Nvidia SLI / AMD Crossfire installations with a hardware bridge.


While the background is active, the Wallpaper engine will consume some of your computer’s GPU and CPU. The best approach to avoid this is to instruct it to halt the background while you use another software. This is the configuration I use so that it is only active when nothing else is open and then pauses when I switch to another window.

Wallpaper Engine, on the other hand, strives not to interfere with gaming performance by pausing when another application is maximized or fullscreen. You may also make it pause when another application is active. It is mainly useful if you are usually playing games windowed.
