Hello all
"IL-2 Sturmovik Cliffs of Dover" has been release few months ago. Initial version of the game had some issues so i decided wait for a while until i include it in HyperLobby supported games. After few patches and updates the game feel better and coming time to do something with it ...
The game itself is not fully compliant for HL requirements but its not anything than will break general HL functionality. I have some pending requests to 1C regarding those issues and hope they will implement em in the past. Presure from the community will be helpfull too
Known issues and requirements for the game and Steam settings to run HL correctly:
* Steam must be run and be in online mode.
* Disable "Steam cloud config storage", Click "View>Game list" menu in the Steam main interface, right click "IL-2 Sturmovik: Cliffs of Dover" item "Properties", then click tab "Updates" and uncheck "Enable Steam Cloud synchronization for IL-2 Sturmovik: Cliffs of Dover". Its because HL need mangle your ini files in order to setup game sessions correctly (Same way we do it in IL2 series for ten years).
* Hyperlobby cannot change your name in online game session, you must do it yourself in your Steam profile, Click "Steam>Settings" menu in the Steam main interface, Then click "Friends" tab and change your "Profile name"
* Hosting a game (not dedicated server) will not enter the game server screem like in IL2-1946, you must click it manually via the ingame menu "Multiplayer>Server".
* Dedicated server need special setup. Some hints you can found at 1C forum: http://forum.1cpublishing.eu/showthread.php?t=22038&highlight=dedicated+server .
Rest of other features you know from IL2-1946 working the same way. For users using HL only as game client anything should work without problems if Steam settings meet HL requirements. Before release of HL with support for "IL-2 Sturmovik Cliffs of Dover" became public, we need pass a betatest. If you reading this post and trying to use this beta version of the HL you are part of the testing team. Since it i need you will check this thread regularly and post any issues related to this version of HL.
Any ingame issues (after you esteablish an online game) are game related. You should post those issues in to official game forum
http://forum.1cpublishing.eu/forumdisplay.php?f=189 . It may help developers improve this game since its at this time under heavy development.
I have setup 24/7 dedicated server for testing HyperLobby client joining capabilites (HL_Dedicated). The closed testing show than this server is not much stable and if you found any issues, report em and i will restart the server.
This version of HL like latest one support automated server session startup via -a commandline parameter, so there is not problem automate dedicated server registration via HyperLobby ...
I update this thread regulary with updated beta release until all known issues will be fixed ...
Beta version 4.2.15 changelog:
* Initial support for game IL-2 Sturmovik Cliffs of Dover.
To download this betaversion you must register hyperlobby forum here because during this open betatest we need direct users feedback."
