What causes Dev Error 6065 while playing Call of Duty?

After analyzing some of the basic troubleshooting steps used to fix the dev error 6065 on Call of Duty, we will be listing the probable causes behind its occurrence in the following list.

  • Corrupted Game Files: If the Call of Duty game files has been corrupted due to a malfunction with the Storage device, the ‘dev error 6065’ will be triggered. These files can get corrupted due to a number of reasons and have to be replaced in order for the game to work properly.
  • Invalid Graphic Card name in Config.cfg: If your Graphics card name isn’t properly entered in the configuration file of the game, the dev error 6065 can be triggered due to an incompatibility during the launching process. It is best to get this name right for the proper launch of the game.
  • Enabled G-sync in NVIDIA: If you have enabled the G-Sync feature in your Nvidia Control Panel and on your monitor, the error 6065 might be triggered because this feature is known to cause some issues with the game’s functionality. It is best to temporarily disable G-Sync to fix the dev error 6065 on Call of Duty.
  • Wrong names of certain folders in the directory: If some folders in your game installation directory have been named incorrectly, the dev error 6065 might be triggered because the game is unable to find the correct files to load its assets. It is best to get these names right before you play the game.
  • High Graphics settings in the game: You might be getting ready to play the game on high or ultra settings but your Graphics Card or some other hardware component on your computer might be getting pushed beyond its limits to play the game at those particular settings. Therefore, it is best to lower the graphics settings at least temporarily to get rid of any such issue.
  • Outdated device drivers: In some cases, outdated drivers might be the reason behind the occurrence of the dev error 6065 while playing call of duty. Therefore, it is best to check for driver updates and install them on your computer to get the latest bug fixes and patches that come with new drivers.
  • Enabled Game overlay: Most applications offer in-game overlays that increase the app’s functionality and often provide some visual input that informs you of certain metrics in the application while you are playing the game. However, these overlays often encounter compatibility issues with some games and it can end up triggering the dev error 6065.
  • Game unable to use DirectX 11: You might’ve moved on from DirectX 11 long ago but it is possible that some component on your computer or the game itself is using Direct X 11 either completely or partially to load certain assets. It is best to have the DirectX 11 enabled alongside with DirectX 12 to ensure complete functionality.
  • Enabled Overclocking in BIOS: Overclocking is often used to increase the computer’s hardware performance by pushing beyond the factory limits. It is, however, always recommended to overclock with extra caution to prevent incompatibilities. Therefore, it is best that you temporarily remove your overclock from the Bios and check if that fixes the issue.
  • RAM not inserted in its slots properly: As absurd as it might sound, the RAM stick can sometimes be incorrectly installed due to which the dev error 6065 is triggered while trying to play Call of Duty. It is best that you check your RAM Stick and push it in completely to ensure that this is not the case with you.
