My 2070 SUPER VR settings and suggestions (Index - SteamVR) šŸŸ¢

This file is a stub (0 bytes) and Iā€™m not sure it is actually working with the App Compat flags (I tried this one in the past and didnā€™t see any change). Iā€™ve also tried the full path into WindowsApp but this didnā€™t seem to make any difference either to me, but this was quite a few months ago already (It might have been during the alpha prior Aug 2020).

UPDATE: Actually you can manually type the path into file explorer and this opens the FS2020 WindowsApps folder nicely.

If you have the MS Store version:

  1. Open file explorer
  2. Click on the ā€œPath Barā€ (where it shows ā€˜This PCā€™ by default)
  3. Copy/Paste the following:
    C:\Program Files\WindowsApps\Microsoft.FlightSimulator_1.12.13.0_x64__8wekyb3d8bbwe

When disabling full screen optimizations it is indeed creating an entry in the registry:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Key:

C:\Program Files\WindowsApps\Microsoft.FlightSimulator_1.12.13.0_x64__8wekyb3d8bbwe\FlightSimulator.exe

Data:
~ DISABLEDXMAXIMIZEDWINDOWEDMODE
