As the title suggests after switching to DX12 my sim is not even loading. Is there any way or a file or something I can edit to revert the DX12 setting?
Same here.
UserCFG.opt - just look for DX12.
Anyway try just restarting your computer. There was at least one Beta build which caused a CTD on startup for me and shutting down + restarting the computer just fixed it.
I have restarted my PC several times, even changed drivers just incase I didn’t have to go searching for this file. Where is this UserCFG at?
Found it under AppData\Roaming\Microsoft Flight Simulator

How to switch to dx11? When I go to my “user cfg” file I change d3d12 to d3d11 I save, but when I launch the game the file automatically returns to d3d12.
This is incorrect. If you go back into your user config file, you will see “PreferD3D12 1” Change the 1 at the end to a 0 and save.
Edit: I had it backwards at first…need to change 1 to 0.

Thanks for the solution on the config file.
But has anyone found a solution to the crash on startup in DX12? This just started happening to me.
Hi @Editer ,
Can you provide your PC specs - particularly graphics card & driver version. Are there any error messages in either the Application or System logs in Windows Event Viewer?
Hi @SmotheryVase665! Core i9-13900K, 64GB, RTX 4090, Win 11. Latest Nvidia drivers, but also tried rolling back to 552.22.
Just checked the crash log in the Windows Event Viewer and got this:
Hmm, WWTSF.dll does not appear to exist on my PC - perhaps it is a file installed by Steam? (I’m on the MS Store version).
Okay, here’s the weird thing. I searched for WWTSF.dll on my PC, only found it in my temp folder (four copies contained within temp folders), deleted all of those, and now DX12 doesn’t crash.
Super weird.
Running a deep malware scan overnight just to be safe!
Did a quick search for the file - see
