Check the status of the service. If you are on PC, make sure you aren’t behind any firewall or security program – to counter that, you can add modern warfare 3 executable to your firewall exceptions list. Port forward 3074 (UDP and TCP).

You may get the error “The game session is no longer available.” Enabling UPnP, forwarding port 3074, or placing your Xbox 360/PS3 in your router’s DMZ to resolve this issue.

Thanks chuba2 for explaining it in detail.

22# Modern Warfare 3 Low Textures Graphics Fix
If you are experiencing low textures quality when playing Modern Warfare 3, use Native Image Quality in advanced graphics options and you will see textures quality improved over whatever settings you were using before. There are five settings here – Low, Medium, High, Extra and finally Native. Remember to switch to Native quality for good graphics – Modern Warfare 2 quality. It’s sad that I have to say this ^

23# Modern Warfare 3 FOV Fix
If you don’t like the default FOV setting in Modern Warfare 3, use the Widescreen Fixer to change the FOV and choose correction monitor resolution.

24# Mouse Sensitivity Changes Temporarily
If your mouse sensitivity changes temporarily when playing Modern Warfare 3, close all the applications running in the background to fix the issue.

25# Can’t Find Server Browser or Dedicated Server Option
Sadly, you have to enable these under Dedicated Server Options first before they become visible.

26# How To Join a Dedicated Server

  1. Enable the server browser in the options menu. Options > Dedicated Server.
  2. When you enable that option, you will have servers available in the multiplayer menu.
  3. Select Servers and find the one with low ping.
  4. Hit Connect to join your favorite server.

27# Crash To Desktop
Often occurs due to any missing file – in this case, it has been found that Verifying the game cache in Steam fixes the problem.

28# DirectX Has Encountered Unrecoverable Error
Same old, same old. You can try Modern Warfare 2 fix for this issue. It will work since both games have been developed using the same engine.

Go to ‘Control Panel’ > Display > Screen Resolution > Select Advanced Properties > Click on the Troubleshooting Tab (It may not be clickable. In that case, update your Video Card Drivers and DirectX) > Get Hardware Acceleration Bar to ‘None’ and finally, Untick ‘Enable Write Combining’.

Note. You can follow the detailed step by step instructions here.

29# Modern Warfare 3 Lag Fix
Set your graphics image quality to Native and all the lag problems will become history.

30# Modern Warfare 3 FPS Fix
If you can’t get the max/stable frame rate in Modern Warfare 3, make sure you have Vertical Sync set to off.

31# IW5MP.exe has Stopped Working
Connect the DAMN! microphone. It’s an old Call of Duty 4 error still creeping the modern warfare games. You can also try turning Anti Aliasing and setting the graphics to low but the first workaround would most probably fix your issue.

32# Unable To Connect To Host
See our NAT Guide and Portforwarding tips above to resolve your connection issues.
