SYMPTOM
While adjusting video settings, or multi-tasking by alt-tabbing to other applications, LotRO crashes, generating "Game Error [105]" and/or "Game Error [128]" and then the "lotroclient has stopped working" error.
CAUSE
From a user perspective, it's always difficult to determine actual
root cause. However, it seems that the
catalyst for this issue is the latest "Windows Fall Creator's Update" combined with nvidia gpus, and using DirectX 9 as the in-game selected "Graphics Hardware Level." Those using DirectX 10/11 in LotRO seem to be unaffected.
SOLUTION / WORK-AROUND
On your computer. . .
- In your Documents folder, find the "The Lord of the Rings Online" directory.
- In that directory, open the "Userpreferences.ini" file in notepad (or any text editor).
- Locate "AllowFakeFullscreen" and make sure it is set to "True".
- Locate "ForceFakeFullscreen" and change it to "True" (it is set to "False" by default).
. . . with that in place, saved, and the LotRO client launched anew, you should be able to alt-tab, switch between fulscreen and windowed mode, change video settings, and otherwise do everything normally. Note: This is a
different setting than "screen mode" that is presented in the Video Options in-game. And "ForceFakeFullscreen=True" in your UserPreferences.ini will fix the errors specified in this thread for all "screen modes" including "Fullscreen (windowed)".
