1) Verify file integrity through Steam: This makes sure i have the correct files for the latest official version, ie the one before the optional patch.
2) Defragment game files through Steam.
3) Go inside my documents\1c softclub\Il2 CoD\cache folder and delete all files within it and the shaders subfolder.
4) Extract the optional patch into the sim's main directory (if prompted to overwrite existing files, choose "yes").
5) Run the sim and wait for it to rebuild the cache i deleted with the correct files for the new version.
6) Run a quick mission and fly around for a couple of minutes to "force" it to load anything it might need to load.
7) Exit the sim."


No crashes since.

Also be sure to use Winrar or 7zip to unpack the files, not Winzip.
And of course rename the intro video at \\Steam\steamapps\common\il-2 sturmovik cliffs of dover\parts\core\GUI\Logo.wmv to Logo_bak.wmv

How do I verify file integrity thru steam ?
