Pretty much as subject describes it. Using "load random images" from local folder. What I mean by "not instant" is that it seems like its taking 5-10 seconds to register the command. (CTRL+Win+R) Tried to look for any setting for delay, but didn't find one. Its not the "windows7wallpaper changing effect" in fault either, happens with/without it. DisplayFusionHelperWin8.exe is the process taking more than it seems sensible. 100% usage for 1 core for around 10-20 seconds after wallpaper change key combo has been pressed.

Windows 8.1 x64 Pro RTM

Not a major thing in any way.

Keep up the good work!

Tried that, no difference. Seems that all PNG files are converted to JPG (because of compatibility with login screen?), is there something that DF does to JPG's? Some PNG's are around 3.5 MB, conversion time+moving them to correct folder might explain some of this. Windows is installed on SSD, wallpapers are loaded from 2nd HDD.

I also have this problem, on two different computers. I always assumed the delay was a limitation of DisplayFusion. Is this the case?

I don't suppose ~750 1080p and ~60 1440p wallpapers is considered huge amount? Glad I'm not alone though, not going completely mental.

Did several manual changes between:
2013/09/24 00:26:19.948
2013/09/24 00:27:05.427

Same kind of behavior with 5.0.1 too. Might've been lucky getting those 3 sec ones that time. I could swear that I've indeed seen 5-10 sec changes.

Wow, didn't expect things to happen this quickly. I'll definitely give the beta a try right away.

Cheers
