If you downloaded DisplayFusion 12.0 and are having issues with languages please re-download and re-install. We have repacked the release as 12.0c with the languages fixed.
I use DisplayFusion on a pretty old desktop with only 8GB of RAM. I was using 9.9 but yesterday I decided to upgrade to the latest beta version. Since I try to save as much memory as I can, I noticed that the value today shoot up quite a bit compared to normal.
After looking into it I noticed that v10 Beta 22 was using 175 MB of memory.
I tried downgrading and v9.9 memory usage dropped down to 86 MB.
That's an increase of double the memory between versions: 175 - 86 = 89 extra memory.
Maybe you can have a look at that for a future beta?
Yes. I'm using the same wallpaper I had with version 9.9.
I have 2 monitors: 2560x1440 (main) and 1920x1080.
Screensaver is also managed by DF, and extended between monitors in case it makes any difference.
