Modern Warfare 3 Crashes, Errors, Freezes, FPS, Elite, Lag, Connection, and Fixes


The billion-dollar franchise returns for another commercially successful year. Modern Warfare 3 may not have scored all the good reviews but it still managed to sell 6 million copies to date and it’s just the launch day.

If you bought the game and are experiencing any technical difficulties in running Modern Warfare 3 smooth on your console or PC, refer to our troubleshooting guide for the workarounds.

1# Cod Elite Down – Can’t Log In
Call of Duty Elite is under maintenance for load-balancing. If you can’t log-in, give it a day or two and it will get online.

2# Call of Duty Elite – Bugs and Crashes
If you experience anything like this, don’t worry, it will be fixed soon! says developer.

3# Invalid GamerTag – Can’t Redeem Double XP Code
When you try to redeem your double XP code, it gives Invalid Gamer Tag error.

4# Can’t Connect To Online Games – Call of Duty Elite
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).
Make sure you have port forwarded UDP: 27000-27015, 27015-27030 and TCP: 27014-27050 that are required for Steam Connection.

5# Playstation 3 and Xbox 360 – Can’t Connect To Online Games
Check the status of the service. Disable firewall/security program and re-run the game. Port forward 81, 3074, 3075, 3478, 3479 (UDP) and ports 80, 443, 3074, 5223 (TCP) for Playstation 3. Port forwarded UDP: 3658 for smooth communication. Put your PS3 into DMZ of your router.

If you still can’t connect, disconnect your router and try again. 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. If it’s PS3, try deleting PS3 browser cache and browser’s cookies.

6# Prestige Token Not Showing
Primarily a server issue, will be fixed soon! If you still don’t see your prestige token, contact Activision.

  • Left click on your gamertag on the bar at the top right.
  • Select “Profile”.
  • Left click on the Plus sign next to “Link your Facebook Account”.

To link your YouTube account to the Call of Duty ELITE service, navigate to the Career page and click on the Vault anchor link on the right. There, you should see a “Link with YouTube” button. Clicking this will redirect you to YouTube and ask you to sign in.

Now, all you have to do is click “Allow Access”, and you’ll be taken back to the Call of Duty ELITE site. Now, every time you upload a video from in-game, your videos will be displayed shortly afterwards in your “Vault” section on the website.

14# Rank Reset
If your stats are reset, Modern Warfare 3 will restore them using the previously stored backup. You may lose all the progress you made in your last play-through the game.

15# Crash and Freeze During Install

Set your desktop to a resolution of 1024×768, 32 bit True Color.

For Windows XP

19# Where is 3D Support ?
In Battlefield 3.

20# Lost connection to Host
Mostly this error occurs when server times out.

21# How To Open Your Nat To Solve No Sync In Co-op
Your router address should be something like this http://192.168.1.1 just copy and paste into your browser then find where your router stores your NAT/PAT settings they are usually in the advanced section of the http interface.

TCP: 3074
TCP: From 27014 to 27050

UDP: 3074
UDP: From 27000 to 27030

Add a new rule, then in the pull down menu you should have something like “create new rule” then just add the numbers in external and internal ports, then the protocol TCP or UDP, then to what computer on your network should use them, reboot your computer and the router and your MW3 should be Nat Open after that. 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.

We will add more of the general issues experienced by the players with workarounds to fix these issues. Meanwhile, if you face any other issue, let us know in comments below!

    • joe

      i can get into a game, but then after the i finish playing the second match, the third match i get stuck on either “setting up game” or “waiting for players” and then “connection lost”. once that happens i try to re-enter and the “connecting to online” shows up and takes 5+ minutes, every now and then the “can’t connect to steam” shows up. i have no idea whats going on. NAT is open. pc definitly can run the game, verified twice. i have to exit steam, then re-enter to get in a game, every 2 matches. whats weird is i keep getting into “lockdown” while other maps i basically stall at the “setting up game” or “waiting for players” and then time out or disconnect. please help. i really dont know what to do.

      Hey, I have a problem with my settings. I can not change my Texture Quality setting to low. When I set it and back out it just goes back to normal. I can change it to higher settings. I bought the game via Steam. I found a forum on Steam where people had a similar issue: http://forums.steampowered.com/forums/showthread.php?p=26553319&posted=1#post26553319

      Still no solutions on it. Is there anyway I can fix this issue or give additional details to help get it fixed. I didn’t have this problem before the last patch.

    • Art Vandelay

      Friend lives in central florida, keeps complaining of lag and dashboarding out on xbox 360. We usually make fun of him but now that he’s mentioning the issues he’s seeing just connecting to games I believe he has issues and it’s not lack of skill (he’s a good COD player). He says he never gets in games when it is looking at < 50ms ping. Always takes a while and gets up to < 150ms ping before he's able to join a game. Strange thing is he's got a fast connection, speed test shows download speeds of 40Mps. He's hard wired from his router and even tried coming straight out of the modem but says no matter what he does, always takes a while to join games and so far the game has been unplayable and frustrating with not getting hit markers consistently. If he looks at bandwidth in xbox he's at what the max says which I believe 10,000kps. On the flip side, I live in ATL, have an ok connection (20Mps), I use wireless and my bandwidth in xbox shows only about 2,000kps most of the time. Yet, I have never seen it get me in a game other than those at < 50mps ping. I alwasy quickly join those games. What can he do to troubleshoot? I think you can rule any router/firewall settings out as he's tried coming straight out of the modem. Could it simply be his location and even though he's got good speeds, he's not pinging anything at < 50. This is baffling to me, doesn't make much sense. Play one game with him and listen to the complaining the entire time and you'll want to get this fixed for him as well. Yeah c'mon, any help is greatly appreciated.

          Happened to me as well today, lost 6 HOURS of game play! Unbelievably annoying.
          Is there any way I can try to stop it from happening, or is it just unfortunate?
          Also, is there any chance my progress may be restored?

          • http://segmentnext.com Zawad Iftikhar

            Your stats should restore in 24 hours and if they don’t, contact Support because they will most probably have a back up saved.

    • Mewik

      everytime i open mw3 (pc) it works for a few seconds then steam disconnects. It will not reconnect until I exit mw3, sometimes it reconnects, other times when I exit my network connection is off and wont come back on until I unplug the network cable and plug it back in. I have tried rebooting the router but it does not reconnect by itself and I must still unplug the cable. So I dont think its related to the router.

      Im a bit lost, when I first installed and booted I played for about an hour with no issues, then when I tried to play mw3 a bit later I encountered all these problems.

      any ideas?? lol
