Game crashes after 15-20 minutes into battle

This problem has been happening long before the La Royale update.
After around 15-20 minutes into the battle, my game just freeze followed by sounds stuttering, 1-3 fps drop, device hang, and sometimes BSOD, I had to force restart my device OR I keep task manager in the background and kill the aces.exe from it. This problem also makes my device freeze until I killed the process and wait 5-7 minutes.

First thing first, The game didn’t give me a crash report. So, I checked my Event Viewer and got this error after the game crashed.

Session “dc3a3596-71e1-45a3-b2ea-39ad5322fe51” failed to start with the following error: 0xC0000022
Session “dfa2c640-651d-488d-a479-2fd7a7ca6e29” failed to start with the following error: 0xC0000022

This is what I did for trying to fix this problem

  • Verified game files, through steam and launcher - no fix
  • Installed the game just from launcher or steam - no fix
  • Run the game as administrator, and also reinstalled EAC as administrator - no fix
  • Reinstalled WarThunder many times - no fix
  • Updated my driver to newest version and rollback to previous driver - no fix
  • Installed the game in clean windows 11 and windows 10 - no fix
  • Increased the size of pagefile and readyboot - no fix
  • Updated windows to latest version - no fix
  • Activated DirectPlay from Legacy Component in Windows features no fix
  • Underclocked my device with MSI Afterburner - no fix

After all that effort, I’m sure that the problem is my device (Lenovo V14 G2 ITL w/ Nvidia MX350), so I need help with this specific problem. I really love this game and I don’t want to stop playing War Thunder just because of this problem. Thank you.

Could you upload a current dxdiag.txt log to your post. Or if necessary PM one to me.

i’m also experiencing the same issue and have tried so many different methods just like you and yet I reset my entire PC just to face the same issue again


Here’s the DxDiag.txt, sorry I have been gone.

DxDiag.rar (20.5 KB)

Is the game installed on your SSD C: Drive, or your HDD D: Drive?

Looking at the dxdiag, I don’t see anything that sticks out, other than you may need to update your intel UHD graphics drivers. Some times that can cause the graphics switching to not work correctly if they are way out of date.

Also, make sure that the game is using the MX350, and not the UHD integrated graphics.

My game is installed on SSD C: Drive. Last time, I also installed it on my HDD. Same issue. I already set my game to use MX350 instead of integrated graphic. Right now, I’m updating my intel driver with intel assistant tool to Version: Release date: June 21, 2023 because auto-update didn’t check it. Let’s see if it works.

I’ll update if there’s any crash again.

My game crashed again after 6-8 GRB match, around 2 hours. The game returned to normal (no lag, no freeze) after I returned to the menu. The error I checked from event viewer Session “dc3a3596-71e1-45a3-b2ea-39ad5322fe51” failed to start with the following error: 0xC0000022 still exist.

Also here’s the fresh DxDiag.txt. Thank you.
