Common Problems

  • World of Warcraft is running slower than it should
  • My FPS in World of Warcraft is really low

Slow and choppy gameplay can have a variety of causes. Check your latency before continuing with the troubleshooting steps below. If your latency is high, check our connection troubleshooting article.

Note: Before you troubleshoot this issue, check the World of Warcraft System Requirements to make sure your computer's hardware meets the minimum requirements.

  1. Reset your user interface to make sure your files and addons are not corrupted.
  2. If any in-game settings are set too high for your computer, you may notice a performance loss. Lower your in-game video settings in the System menu to improve performance.
  3. Update your drivers to resolve any compatibility issues.
  4. If you're playing on a laptop, optimize your power management settings and graphics options for gaming.
Advanced Troubleshooting
  1. Try closing background applications to resolve any software conflicts.
  2. If your computer locks up and becomes unresponsive, check for overheating components.
  3. If you are running the game in Crossfire mode with two AMD graphics cards and you notice a significant drop in your FPS, run World of Warcraft in 32-bit mode.
  4. If you are using a laptop with NVIDIA Optimus technology, you must force your computer to use the NVIDIA graphics card. See NVIDIA's support article for assistance.
  5. Try running the game in a window and with no sound. You can enable windowed mode in the in-game System menu by changing the graphics Display Mode dropdown to Windowed. You can disable in-game sound by unchecking Enable Sound in the system Sound menu.
  6. Try selecting a lower setting from the Sound Channels dropdown in the System > Sound menu.
    Note: Some add-ons may set Sound Channels back to High after installation.
  7. Run ScanDisk and defragment your hard drive to try to repair any bad sectors.
    Note: Do not defragment a Solid State Drive (SSD).
  1. Run Software Update to check for pending updates to software, drivers, and firmware.
  2. Reset your user interface to make sure your files and addons are not corrupted.
Advanced Troubleshooting
  1. If your computer locks up and becomes unresponsive, check for overheating components.
  2. Lowering the maximum frame rate can improve performance by preventing out-of-focus objects from affecting your frame rate.
  3. Try selecting a lower setting from the Sound Channels dropdown in the System > Sound menu.
    Note: Some add-ons may set Sound Channels back to High after installation.
  4. The System Management Controller (SMC) controls power flow and fan speed. If it's not working properly, it can affect game performance. Reset the SMC.
  5. Missing system files may cause encryption failures. Download the latest Combo Update for your specific OS X version to restore missing files.
  6. Repair Disk Permissions to resolve any permission conflicts with logon modules.
  7. Run the Apple Hardware Test to make sure there are no physical problems with your hard drive.
  8. Some MacBook Pro models have two separate graphics cards, which may require manual setup. Make sure your MacBook Pro is set to higher performance or automatic graphics switching is disabled.
