Performance issue of video wallpapers

[i0nTempest]

So I have 3 mornitors, one 1080P@240Hz, one 1080P@144Hz, and one 4K@60Hz. I have WE running on my two 1080P sereens, both using video wallpapers. The performance is good at the beginning, but low FPS and tearing will occur in about a few minutes. It won't always happen, but when it happens it's reappy annoying. Problem can be temporarily solved by switching to next wallpaper, but it will occur again. Is there any settings i can change to improve performance?? I have shark007 advanced codecs installed.



Besides that, the reason that I don't run WE on my 4K monitor is that it will greately lower the FPS on all three mornitors. Can I force the resolution to be 1080P?

Which graphics card do you have? If it's Nvidia, do you have Geforce Experience installed? And if not, is any other recording program active like AMD ReLive or Windows GameDVR?

I have the exact same problem!

I set the same video wallpaper separately on both my screens (which are the same exact model), and it works fine for 5-15 minutes and then suddenly the framerate tanks for no apparent reason. This also happens when the computer is left idle with no other applications running, so it's not a resource issue.
As in OP's case. the problem goes away if I switch wallpapers back and forth or if I change any settings that cause the wallpaper to refresh. Then it takes 5-15 minutes beofre it happens again.

I have no problems with scene wallpapers.

I have an Nvidia GTX 970 and the old version of GeForce Experience is installed, with ShadowPlay activated (though not for desktop recording).

Can you try to just disable all its in-game features, since it thinks Wallpaper Engine is a game? This exact same issue did occur because of screen recorders before, but only way to know for sure is trying to disable them on the PC it occurs.

Videos are streamed by default, it could also be caused by something hogging the hard drive temporarily which would make the video choke for a moment. Could you check for hard drive activity in the task manager when it happens?

I've disabled ShadowPlay now, so I'll wait and see if it happens again. The other PCs I use Wallpaper Engine on don't have ShadowPlay enabled, so it could very well be the culprit.
But if it is, is there any fix for this? I don't want to have to turn ShadowPlay on and off every time I play a game...

I'm waiting for Nvidia to fix it (literally a 10 second job - adding 4 .exe names to an existing exclusion list they have). But first make sure it really comes from there, yeah.

It's been an hour since i deactivated ShadowPlay and restarted WE and it hasn't choked yet. Seems like we just have to wait for Nvidia, unless there's a way to manually add entries to the exclusion list locally?

There could be a way, but you have to modify one of their DLLs with a hex editor. I haven't tried out if it works though. But if something goes wrong then things could go really bad.

I have AMD GPU powering 2 of my screens and an external GTX 1070 powering the 240Hz one. I have GeForce Experience installed, but I think I have disabled the shadowplay.

Maybe you could do this: http://steamcommunity.com/app/431960/discussions/2/1473095331509794520/ ?

WE actually choked again just now and I got FPS drops. Windows Performance Monitor showed some pretty heavy disk usage, but I'm not sure what caused that. I don't know how that correlates to the other times I've had issues, but it's probably a different cause since it's taken 10 hours to happen now.

I'd assume in-memory video loading is preferable in terms of performance and HDD health? I've set it to that now, anyway.

If you don't have an SSD, yes. Also you might want to use the beta version because I think I managed to improve it there and stop it from crashing with .wmv files. It took me a lot of poking around because the info I needed for that doesn't seem to be documented by MS.
