Issues fixed[edit]

Frequent crashing during missions[edit]

On Windows 10, the game will crash to desktop within a few minutes of starting a mission.
Set Windows 7 compatibility mode[citation needed]
  1. Go to <path-to-game>. Right-click Ace Combat_AH.exe and select Properties.
  2. On the Compatibility tab, check the box next to Run this program in compatibility mode for: and select Windows 7 from the drop-down box.

Crash to desktop after mission complete[edit]

Game repeatedly crashes to desktop at the end of certain missions before the cutscene is displayed.
Switch to windowed mode[7]

Switching to windowed mode before the end of the mission and then switching back to fullscreen afterwards appears to resolve this problem.

Update graphics drivers[7]

Others have reported that updating graphics drivers to the newest version resolves this issue.

Title screen control glitch[edit]

Game does not respond past the title screen, merely cycling through all buttons regardless of whether or not a controller or keyboard is used.
This issue appeared after the Steamworks update.
Disable Bluetooth adapter and not needed input devices[8][9]
  1. Disable computer's Bluetooth adaptor (if it possesses one) in the system tray.
  2. Additionally, go to the device manager and disable Bluetooth adapter in there.
  3. If this doesn't help, disable other input devices (like drawing tablets and joysticks in it).
Remove config files[citation needed]
  1. Go to <path-to-game> and delete input.ini.
  2. Go to %USERPROFILE%\Documents\NAMCO\ACAH\ and delete input_<user-id>.ini.
  3. Try running a game in Windows XP compatibility mode.

Control and graphics settings reset between sessions[edit]

On some systems control and graphics settings do not save after making changes.
For Windows 10, the gfx_settings.ini file must also be created manually. Use Notepad to create an empty file in the ACAH folder.
Create folders for configuration files[10]
  1. Go to %USERPROFILE%\Documents\
  2. Make a folder named NAMCO
  3. Go into the NAMCO folder and make a folder named ACAH
  4. Launch the game
  5. Edit the in-game graphics and controls settings to generate the necessary files

Consistent freezing[edit]

Disable multi-GPU mode[11]
This solution is only relevant for those running Nvidia graphics cards.
  1. Open the Nvidia Control Panel.
  2. Go to "3D Settings" and then "Configure Multi-GPU".
  3. Disable multi-GPU mode.

Screen flickering on Windows 8[edit]
