To fix this, open Nvidia Control Panel > Manage 3D Settings > Program Settings > select the game > select the Non integrated GPU. If you are running War Thunder on a laptop with a dedicated GPU or a system with onboard graphics then chances are, the game isn’t using the dedicated GPU. Players have reported that when they launch the game, the CPU usage goes to 100% and the game just crashes at startup.
This is a bit of trial and error and players will have to set a value and see at which FPS limit the game stabilizes. Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select the game > set the value for “Max FPS Limit”. If the temperature of the GPU is maxing out and then the game crashes then I would recommend locking the game’s FPS at a lower value. Chances are, Easy anti-cheat isn’t the problem here check your GPU for temperature and usage.
Some players have reported that War Thunder crashes randomly while running and for some Easy anti-cheat error. Restart your system and then launch the game, the error 30007 will now be fixed.
