Given the NVIDIA Driver I have to use DX12 however it has terrible performance for me, but if I want to use DX11 I have to launch the sim, wait for it to load then change the DX version and then restart it. Is there a config file I can change prior to loading it?
For the Store version, open your %LocalAppData%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\UserCfg.opt file and look for the line PreferD3D12 1. On my system it is line 16. Change the 1 at the end to a 0 and you will load in DX11 mode. Use Notepad or Notepad++. Do not use Wordpad. Wordpad will mess up the encoding of the file.
Mike’s method works, it will still show DX11 in options but you can check that it’s running on the fps counter. Just change the options setting to 12 before you quit the sim and it will stick.
At the risk of going OT, what format are the files? ASCII?
After many years of editing MSTS files, which are unicode, I’ve learnt to be careful with Notepad (I simply close the window without using the Save command).
Yes they are basic ascii files. You can open them with notepad and edit/save them then launch the game and they will be there. Personally when I make changes to the file after I save it I set it to Read only, so that the game doesnt change it back.
Great, I thought they were but thanks for confirming it.
