So, yet another beta from MG:

Quick patch notes

Extensive investigation showed that crashes were often connected with the “not officially supported” weather module. Examining some user-made missions from some online servers showed that people were using the functionality extensively. We’ve temporarily disabled it which appears to resolve a large number of online crashes.


The investigation also shows that a disproportionately large number of crashes happens while a web browser with a flash video or audio (such as youtube) is open in the background. We recommend temporarily closing your web browser, or at the very least any tabs with open flash audio or video, while playing the game.

A Effects setting was thoroughly rewritten. Setting Effects to Medium will greatly increase average FPS on most machines without greatly affecting visual quality. Note that this setting also affects the visual appearance of clouds.

Many changes to the Flight Model were made, and the work still continues. Please note that the general performance of the British aircraft is much closer to desired envelope, but the information shown on the Boost gauge is scaled incorrectly at the moment.

Known issues: temporarily disabled cloud shadows again; hit decals may appear glitched; some steam effects like punctured water radiators and wing vortices also temporarily disabled.

The main goal of this version of the patch is, once again, to locate and fix any remaining crash bugs. Please continue sending in your logs and crash dumps to This email address is being protected from spambots. You need JavaScript enabled to view it.

Please enable logging in your conf.ini (Log=1). If the game crashes, send us the log file it creates in your [My Documents]\1C SoftClub\il-2 sturmovik cliffs of dover folder, and any .dmp files created in a cppdump folder under the main game installation.

We recommend installing the patch on top of a clean steam installation. To ensure your steam install is clean, please right-click the game in the steam library, and select Properties – Local Files – Verity Integrity of Game Cache.
