If Solution 2 just isn't for you, you can also uninstall GenTool. This may prevent CnC-Online / Revora from working correctly. You will still be able to play online via GameRanger.

Slow game speed

Assuming you have GenTool installed, keep an eye on the yellow number on the left top part of the screen. This number represents your FPS. If it is lower than 25 it means your game will slow down. If it is above 25 then you have nothing to worry about. Note: When playing online the yellow number should be steadily above 35 to prevent the game from slowing down.

Solution 1:

  1. Start the game.
  2. Go to 'Options' in the main menu.
  3. On the left under 'Detail', choose 'Low'.
  4. Click 'Accept'.
  5. See if the problem has been fixed.

Solution 2:

  1. Start the game.
  2. Go to 'Options' in the main menu.
  3. On the left under 'Detail', choose 'Custom'.
  4. Uncheck all checkboxes.
  5. Slide the 'Texture Resolution' and 'Particle Cap' sliders to the lowest they can go.
  6. Click 'Accept'.
  7. Click 'Accept' again.
  8. See if the problem has been fixed.

Solution 3:

  1. Start the game.
  2. Go to 'Options' in the main menu.
  3. On the left under 'Resolution', choose '800 x 600'.
  4. Click 'Accept'.
  5. See if the problem has been fixed.

Solution 4:

  1. Modify the shortcut to run the game in window mode.
  2. Start the game from the modified shortcut.
  3. See if the problem has been fixed.

Solution 5:

  1. Restart your PC.
  2. Disable virus protection on your PC. (Anti-virus uses a lot of processing power. Switching off your virus scanner when you want to play can make a big difference to the game.)
  3. Close all other applications such as Skype, web browsers (Google Chrome, Mozilla Firefox, Opera Web Browser, Microsoft Edge, etc.), Discord, Steam, word processing or spreadsheet software (Microsoft Word, Microsoft Excel, LibreOffice, etc) as well as any other applications that you do not need running.

Problems playing online

"Failed to join - the game is a different version"

This means that your game and the hosting player's game are not compatible. If you have a mod installed you must uninstall the mod for the game versions to become compatible again.

Solution:

  1. Uninstall the game.
  2. Install the game by following the steps outlined in How To: Install C&C Generals.

"Unable to connect to other player(s)"

Solution:

  1. Make yourself a cup of coffee because this will take at least 20 minutes to fix!
  2. Carefully follow all the steps outlined in How To: Fix connection problems.

"Game has detected a mismatch"

Solution 1: (GameRanger only!)

  1. When transferring a map that has a 'map.ini' file you might get a mismatch. After the mismatch close the game and go back to GameRanger.
  2. Start the game and try again. On the 2nd try you should no longer get a mismatch.

Solution 2: (Cnc-online / Revora only!)

  1. You have played a custom map at some point without restarting the game. Close the game completely.
  2. Start the game.
  3. Try playing another match.

Solution 3:

  1. You trying to play a custom map that is new or broken or has bugs. After the mismatch close your game.
  2. Try again but play a different map (official maps are recommended when testing).

Solution 4:

  1. Remove any installed mods.
  2. Remove any additional files you added to your original game.

Solution 5:

  1. Uninstall the game.
  2. Install the game by following the steps outlined in How To: Install C&C Generals.



Solution 1:

  1. Fully restart your PC before you want to play.
  2. Avoid using software that use a lot of PC resources.
  3. If you are using voice chat, use Discord instead of Skype.
  4. Disable any active virus scanners.
  5. Disable any active anti-adware or anti-malware software.
  6. Disable any active firewalls (including Windows Defender Firewall).

Solution 2:

  1. If you have manually overclocked your CPU, set it back to its original clock speed.
  2. If you have manually overclocked your RAM, set it back to its original clock speed.
  3. If you have manually overclocked your graphics card, set it back to its original clock speeds.

Disconnection menu mid-game (dc bug)

This bug occurs because specific online game data has been blocked, either by a firewall or otherwise.

Solution 1:

  1. Wait approximately about 10 minutes with the disconnection menu showing. Do not write in the chat, just wait patiently.
  2. If the disconnection menu goes away and the game continues, do not do anything for a full minute. Do not touch your mouse or keyboard. If all players do this there is a chance the game will recover.
  3. After a full minute of game stability continue playing the match.

Solution 2:

  1. If you are using voice chat, use Discord instead of Skype.
  2. Disable any active virus scanners.
  3. Disable any active anti-adware or anti-malware software.
  4. Disable any active firewalls (including Windows Defender Firewall).

Solution 3:

  1. Avoid playing with players who are italics with one another.
  2. Ideally only play with players who have their UDP port 16000 opened. If you do not have your port forwarded, check out: How To: Fix connection problems.

Slow game speed when playing online

Solution 1:

  1. Assuming you have GenTool installed, keep an eye on the yellow number on the left top part of the screen. This number represents your FPS. If it is lower than 35 it means the online match will start to slow down. In this case, follow the steps outlined in Slow game speed.

Solution 2:

  1. One of the players you are playing with is causing the slow-down because their FPS is below 35. Ask in chat for everyone to say the 'yellow number in the left top corner'. If a player gives a very low number like 16, you know will know that this is the player causing the slow-down. Notify the player to fix their slow game speed issue and refrain from playing with this player until their issue is resolved.

Delay when commanding units

This is also known as 'internet lag'. GenTool provides a latency counter in the left top of the screen in a grey-blue color. The lowest latency you can have is 10 (which is near-instant) and the highest latency is 64 (which causes a very big delay between actions).

Solution:

  1. The solutions are the same as those outlined in Frequent 1-second game freezes.

Frequent 1-second game freezes

This is known as 'internet lag'. To check your internet speed try running a speed test. See the table below to see what your download and upload speeds should be for optimal latency:

Solution 4:

  1. Upgrade your internet to meet the requirements outlined above.

Solution 5:

  1. Play online matches on Revora / Cnc-online instead of GameRanger as GameRanger tends to cause more lag.
