Battlefield 2042 - Direct X Error - Direct x function "hr" failed

I get the same error running on 4070ti

Hi NightShiftEa​ 
First of all, thank you for your DxDiag,
After analyzing your error and your Dxdiag, I noticed that you still have the Intel UHD 770 iGPU enabled alongside your RTX 3070 Ti. It's not ideal, but normally it shouldn't cause any problems. You just need to do the following: 

In Windows ->Display settings -> Graphics settings -> assign your Battlefield 2042 to “High performance (RTX 3070 Ti)".

Next, we will focus on your error.
Often, this error is related to a corrupted cache, which frequently triggers an E_UNEXPECTED error.....

- Press Windows + R

- A page will open (image) enter: %LOCALAPPDATA%\D3DSCache
- A window will open 
- Select everything (file) and delete it. (Windows will automatically recreate them)
- Do the same for: %LOCALAPPDATA%\NVIDIA\DXCache

Next, I recommend installing Nvidia driver version 577.0 -> https://www.nvidia.com/en-us/drivers/ 
This driver is currently the most stable for Battlefield 2042.

- Restart your computer
- Start the game 

Let me know ! 😄

Hello! I did everything as you described. But there is new error. Also i can't delete all files in %LOCALAPPDATA%\NVIDIA\DXCache. Also i have for some reason two BF2042.exe in Graphics. All in screenshots :(

yes it worked but now my computer after ~30 minutes of playing suddenly goes into reboot for no reason :( 
before I reinstalled the OS to Windows 11 - the game worked perfectly with exactly the same PC specs

Great now we just need to find the "reboot" problem.

You can try the following:
-Install version 577.0 of your NVIDIA graphics card > https://www.nvidia.com/en-us/drivers/ 
-After installing the update, restart your PC.
-Then launch your game.

Let me know !

everything works, thank you! 

You're welcome
