If your game client is crashing, it’s typically due to a few common causes.
First make sure that your computer meets the requirements to play the game. The requirements can be viewed here. If you do not meet the requirements listed (64-bit Operating System, 3 GB+ of Memory, etc.) the game will not run correctly.
Outdated or incorrect/corrupted video and/or sound card drivers
Make sure you have the most up-to-date video and sound drivers available for your system. Often you can find these by checking your system manufacturer's website and visiting the driver update page for your system model. You can also download updated drivers directly from your video or sound card manufacturer if you know what type of card it is. ATI and Nvidia also offer "automatic driver" installations if you know you have an ATI or Nvidia card but do not know what the model is.
Using Graphics settings that exceed system specs
Try using the Auto Config option in the Advanced Options if you have not already done so. The game will determine what settings will be best for your computer. If you are using custom video/graphics settings via the Advanced Options menu in-game you may experience instability if you set graphics to a level too high for your system. In particular, the higher texture settings in Shadow of Mordor required a fairly powerful computer. You can check the Advanced Options menu and highlight the Texture setting to review the video card memory requirements for each Texture Setting. It is not recommended that you select a texture level higher than what is listed for your videocard's memory (visible in the bottom right of the Advances Options screen). Try lowering these settings or using the Auto Config option if you are experiencing problems or are unsure of what settings to use.
Make sure the game is using the correct video card in your system
For systems that have more than one video card (often a dedicated video card for games and an "integrated" card for general use), it is possible that your system is directing Shadow of Mordor to use the wrong card. If you check the Advanced Optioons menu in-game you will see the card that is currently being used at the bottom right of this screen. If this is the incorrect card, you can change this by going to the Video section of the Options menu and changing the "Display Adapter" to your desired video card.
Corrupted or incorrect DirectX installation
Try updating Direct X by installing the most recent version available. This is the software the game uses to communicate with your PC, so if the installation is out-of-date or corrupt it can cause crashing.
Overclocking or Turbo Boosting a processor/GPU
If you are Overclocking or Turbo Boosting a component in your computer, we strongly recommend resetting the component or components to chipset manufacturer specifications, as doing so may prevent any crashes from occurring in the future.
If you’re using ‘Intel Turbo Booster’, please disable this feature, which is found in your Computer Bios settings.
Corrupted installation of the game
You may have a corrupted installation of the game client. Try uninstalling and reinstalling the game client.
If you have tried the steps above and the game is still not running well for you, please contact Customer Support using the Ask for Help link above.
