In addition to resource limitations, crashes in Modern Warfare 3 can result from corrupted game files or the simultaneous use of overlay applications with MW3. Having pinpointed potential causes, let’s explore solutions to MW3 crashes.
1. Rename MW3 Folder
Renaming the MW3 folder can prompt battle.net or Steam to recognize that MW3 is no longer installed, effectively acting as a manual uninstallation without removing the actual game folder.
2. Turn off Discord and Steam Overlay
Overlay applications can consume substantial system resources and potentially cause crashes. Disable the Discord and Steam overlays.
3. Verify the Game Files
Corrupt game files can also cause crashes. Verify and repair game files for Steam and Battle.net.
3.1 Steam Launcher
3.2 Battle.net
4. Change Priority to High
Setting the game’s priority to high in Windows directs the system to allocate maximum resources to MW3, potentially solving the crashing issues.
5. Reduce the Graphics Settings
Lowering graphics settings can decrease memory usage and prevent crashes.
6. Close Other Background Processes
Excessive background applications can consume memory and impact performance. Disabling or closing unnecessary applications can improve MW3 operation. If the crashing problems persist, consider reinstalling MW3 onto an SSD (Solid State Drive) or NVMe (Nonvolatile Memory Express), which are faster than traditional HDDs (Hard Disk Drives). Additional troubleshooting methods, including reinstalling the GPU driver and removal of overclock settings, are detailed in the MW2 crashing guide.
