Get Call of Duty to play better and faster

Or in the superlative, play fastest

The move away from CoD%26rsquo;s WWII origins was met with much scepticism. Happily, fears proved unfounded, and the developers%26rsquo; efforts were rewarded with the best-selling game this Christmas, shifting half a million copies in December alone on various formats. Still, no one%26rsquo;s perfect, and the devs should probably stay in their military issue flak jackets while we ponder some of the more common technical issues you%26rsquo;ve had with the game.

CoD4 says it can%26rsquo;t find a file to start playing
Some people have reported that after installing the game - and patching it to version 1.3 - they%26rsquo;ve been hit with this message when they try to start playing: %26ldquo;ERROR: Could not find zone %26lsquo;C:\WINDOWS\zone\english\code_post_gfx.ff%26rsquo;.%26rdquo; If re-installing the game doesn%26rsquo;t help, there is a workaround: simply locate the folder %26lsquo;Call of Duty 4 - Modern Warfare%26rsquo; in the installation directory and copy the entire folder called %26lsquo;zone%26rsquo; from there to C:\Windows.

There%26rsquo;s a problem with iw3mp.exe - it says it needs to close
You may find that there%26rsquo;s a problem with iw3sp.exe, too. More often than not, this is an issue with the audio engine, 32-bit processors or older and integrated soundcards. Try fiddling with the sound settings - some people have found that just plugging in a microphone works. If you%26rsquo;re running an older Athlon processor, try renaming %26lsquo;mssmp3.asi%26rsquo; to %26lsquo;mssmp3.bak%26rsquo; (you%26rsquo;ll find it in the %26lsquo;...\miles%26rsquo; folder).

Every time I try to change resolution, CoD4 just crashes
Are you running XFire, perchance? Despite being a great tool for in-game chatting and server browsing, it has a known conflict with CoD4.

All I can see are white blobs on a black background
Don%26rsquo;t worry - you haven%26rsquo;t been hit by a hippy flashbang. Chances are you%26rsquo;re running an nVidia card and have the drivers set to %26lsquo;Override any application setting%26rsquo;. Try changing this to %26lsquo;Off%26rsquo; or %26lsquo;Enhance the application setting%26rsquo; and the world should come swimming back into focus and colour.

When I use the iron sights on my rifle, everything goes blurry
Hopefully this will be fixed in the next patch. For now, just turn off Depth of Field.
