How to Fix War Thunder Not Using GPU and Crashing at 100% GPU Usage
Before you start the following troubleshooting methods, quickly go through the below steps and check if they worked.
– Restart the game as well as the PC
– Make sure your GPU drivers are updated to the latest version
– Close all programs and tasks running unnecessarily in the background (Press Ctrl + Shift + Esc and right-click on the tasks one by one and press “End Task”)
– Repair game files: Go to Steam Library >> Right-click on the game >> Properties >> Local Files >> Verify integrity of game files
– Provide admin permission to the game. Find out the .exe file of the game and provide it admin permission.
After going through these quick methods, if the issue persists, try the below troubleshooting steps.
Use Dedicated GPU
In case your system has a high-end GPU and the game is not using it, it can cause lagging, low FPS, and other graphics-related issues. In such a situation, you need to use a dedicated GPU to resolve this issue. To do this:
For the NVIDIA GPU
– Go to the NVIDIA control panel by right-clicking on the Desktop
– Then go to 3D settings >> Manage 3D settings
– Go to Program settings >> War Thunder >> select high performance NVIDIA processor and save the changes
– Reboot your PC and check if that worked
For the AMD GPU
– Go to AMD Radon settings by right-clicking on the Desktop
– Next, click on the system tab and select Switchable graphics
– Save the changes and once done, reboot your PC
Disable Windows Game Mode
Some gamers have reported that Game Mode can also cause 100% GPU usage issue in the game so we recommend disabling it and it will help you to resolve this issue. To disable Game Mode, go to Settings > Gaming > Game Mode, and toggle off the Game Mode switch.
Change In-game Graphics Settings
If the issue persists, we suggest trying to change in-game graphics settings. For this:
– Go to Steam Library >> Right-click on the game >> Settings and turn OFF “V Sync” option
– Go to the Advanced settings and set all settings to low or medium
– Once done, restart your game and check if that helped
Reinstall War Thunder
If nothing helped, try uninstalling the game completely and then reinstalling it. This will ensure fixing any corrupted game files.
That’s all for this guide on how to fix War Thunder not using GPU and crashing at 100% GPU usage.
