Our guide will show you How to Fix War Thunder Not Using GPU and Crashing at 100% GPU Usage and optimize your gaming experience.


War Thunder is an online multiplayer game that allows players to control various war vehicles and engage in battles with other players. However, some players have reported issues where the game crashes and does not use their GPU fully, which can hinder their gaming experience and affect their ability to play the game. In this blog post, we will discuss several methods to fix War Thunder not using GPU and crashing when GPU usage hits 100%.

Method 1: Use a Dedicated GPU


A dedicated GPU (graphics processing unit) is a separate component in a computer that is specifically designed for handling graphics-related tasks. If your computer has a dedicated GPU, it is possible that War Thunder is not using it properly. Here's how you can check if your system has a dedicated GPU:

  • For Windows users: Right-click on the desktop and select "Display settings" > "Advanced display settings" > "Display adapter properties".
  • For Mac users: Click on the "Apple" logo on the top left corner of the screen > "About This Mac" > "System Report" > "Graphics/Displays".

Once you have determined that your system has a dedicated GPU, you can follow these steps to set up War Thunder to use it:

  • For NVIDIA GPU users: Open the NVIDIA Control Panel > "Manage 3D settings" > "Program Settings" > "War Thunder" > "Select the preferred graphics processor for this program" > "High-performance NVIDIA processor".
  • For AMD GPU users: Open the AMD Radeon Settings > "System" > "Switchable Graphics" > "War Thunder" > "High Performance".

Method 2: Update GPU Drivers


It is important to keep your GPU drivers up-to-date to ensure optimal performance and stability. Outdated drivers can cause issues with games, including War Thunder. Here's how you can update your GPU drivers:

  • For NVIDIA GPU users: Open the NVIDIA GeForce Experience app > "Drivers" > "Check for updates" > "Download".
  • For AMD GPU users: Open the AMD Radeon Settings > "Updates" > "Check for Updates" > "Download".
