Turn off multiplayer chat

Some users may be using an alternate VoIP program (Ventrilo, Mumble, TeamSpeak, etc.) to chat while playing multiplayer, and may wish to turn the in-game chat off. There is no in-game setting to do so, but by editing an INI file, you can turn off voice chat.

Savegames will start appearing in the wrong order once there are more or around 100 savegames.

Save game slowdowns

Having a lot of savegames can cause the game to momentarily freeze while loading the "Save Game" screen (most noticeable due to music pausing for a second), caused by a CPU bottleneck.

Instructions
