RE: GPU Usage using any mp4 video for Wallpaper

David Innes
1 discussion post
When using a JPG file for the background/wallpaper DisplayFusion has <5% load. When using a .mp4 video as the wallpaper the GPU spike to >30%. It also seems to affect to the GPU usage of Desktop Window Manager >10-15%. When I change the video to anything else...the high GPU goes away. Now I'm sure using 1080 or 4k videos would take up some GPU process...but >30% seems extraordinary. I have tried a number of suggestions such disabling hooks, etc...turning off internet security and other similar apps...windows setting change about auto-color and such, but to no avail. Even small video files run the GPU up to 20%. The videos run fine, it's just the high GPU usage. Attached are some diagnostic files if needed.

Hi David,

Unfortunately we don't have any control over this, as we just use the Windows video rendering libraries. I tested it out on my end, and it seems to be an issue with the "Span image across all monitors" setting. If you set it to use a different image per monitor, or use the same image on each monitor, it should lower quite a bit.
