THIS MOD FIXES NETWORK PROBLEMS IN MULTIPLAYER CAUSED BY THE DEFAULT UNREAL ENGINE SETTINGS.
The background is, the default Unreal Engine settings for multiplayer are set too tight and can cause a bottleneck that ends in lag or rollbacks and delays.

You can and should always have this mod installed for the co-op. I am not aware of any problems. If you experience any problems please contact me.

This mod works in public lobbies.
This mod is compatible with other players who do not have this mod.
This mod only works if the host of the lobby and the client have the mod installed.
Otherwise the default game settings will be used and not the overridden values on the .ini files.
