As mentioned above the new patch should do this, but right before installing a CloD patch you can clean your cache: 'C:\Users\<USER NAME>\Documents\1C SoftClub\il-2 sturmovik cliffs of dover\cache\' by deleting everything in that folder (it will all be rebuilt when you run the game next).

You should probably back up your .ini files in 'C:\Users\<USER NAME>\Documents\1C SoftClub\il-2 sturmovik cliffs of dover\' before you run the beta installer.

This game installs everything important in (one of) two directories so there is not really any advantage to uninstalling/reinstalling over using steam to verify the game files (I don't think this game relies too much on registry entries).

STEAM STUFF

Verify integrity of game cache

1. Load Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.
5. Once the process is completed, the Check Window will automatically exit.

Defragmenting Game Cache Files

Game Cache File (GCF) fragmentation may result in increased load times and sound skipping or stuttering - to ensure your Game Cache Files (GCF's) are stored contiguously, please observe the following process:

1. From the Library, right-click on the game you would like to defragment and select Properties
2. In the Properties window select the Local Files tab
3. Click the Defragment cache files button
4. Once the defragmentation process has completed, you will be presented with a report detailing the extent of fragmentation

Happy Beta Testing!
