What works

  • The USVFS virtual filesystem works well enough for some games (but maybe not others).
  • Installing mods
  • Launching games and other executables
  • Profiles

What does not

USVFS works for some programs, but not others, depending on how they access the filesystem. For example, Explorer++ and exlorer.exe fail to see the virtual filesystem (and the mod files within) unless you navigate through My Computer to reach the appropriate directory. The problem could be bug 47931, as mentioned in MO2 issue 372.

Plugin failures and crashes make MO2 useless until you install certain
Microsoft native components. (See the Workarounds section.)

Occasional crashes.

Endless wine spam in the terminal window: fixme:netprofm:connection_GetAdapterId

Lots of errors in the MO2 Log window, most of which can be ignored.

Lots of little interface glitches, like menus and tool tips drawn incorrectly.

Microsoft.NET doesn't play well with this Wine version, and sometimes leaves mscorsvw.exe processes running in the background.


Manually installing .NET 4.8 got MO2 to launch without complaining about plugin failures at startup. Note: winetricks warns about dotnet problems with Wine 6.0, so the --force option is necessary. (This could be related to the mscorsvw.exe processes mentioned above; it's safe to kill them.)

winetricks --force dotnet48

Manually installing the Visual C++ redistributables got it top stop hanging when opening the Settings dialog.

winetricks --force vcrun2019

Disabling Tools: Settings: General: Check for updates solves the endless fixme:netprofm wine spam in the terminal window.

Interface glitches can often be cleared by clicking elsewhere and then trying again.

What was not tested

  • Nexus integration
  • Most MO2 plugins
  • Anything fancy

Hardware tested


  • GPU: AMD
  • Driver: open source

HowTo / Notes

Bypass failing VFS

This is required to make mods load properly ingame untill VFS works properly in wine. Thanks @Jarrard and @A.J. Venter for this workaround.

VFS script by A.J. Venter is needed for this workaround, get script from here.

  1. Enable mods in Mod Organizer.
  2. Close(or keep running) Mod Organizer and run "python". This will create the VFS for game to recognize mods.
  3. Launch game from skse_loader.exe directly. DON'T launch the game from MO.

Re-run script before game launch whenever new mods are enabled or disabled.

To stop VFS, run "python UNVFS"

Fixing Fonts

Enable subpixel font smoothing

  • winetricks fontsmooth=rgb

Disable render extension for client side fonts

  • Open wine regedit, and inside HKEY_CURRENT_USER\Software\Wine\X11 Driver make an entry for "ClientSideWithRender"="N"
