Client logs (file extension: .clog) are files generated by the War Thunder client and show a reflection of all the actions a user has performed in one game session. As soon as the launcher initialises the start of the game, a new client log is being started, which is finalised when the client is closed (the game session ends). Besides recording the actions of the user, it also records the client-side calculations and has a built-in error catching system that will allow the technical administration to identify game code or synchronisation issues efficiently.
The DxDiag log (file extension: .txt) is a text document that is created by Microsoft's DirectX Diagnostic Tool, showing non-personalized information about the hardware and drivers of your system. The DxDiag log file helps our technical administration to identify whether the problem you encounter is happening due to incompatibilities or issues with certain hardware or driver components on your system. It is especially important with display or sound device issues, as it helps to identify the devices and their drivers easily.
We constantly strive to evolve and improve War Thunder with every passing update, taking into account your feedback, ideas and suggestions as well as delivering new features, locations, improvements, and of course vehicles to expand the game to new heights. One of the key factors that helps us continue to improve the game for everyone is bug reporting; this helps us to identify and fix any issues that unfortunately may occur. Bug reporting allows us to address and resolve matters that may interrupt or interfere with players' experience or improve the historical parts of the game by making things more accurate and true to life.
Client replays are generated when you leave a match or custom battle. They are a recording created from your game’s point of view of the occurences in the match. Client replays tend to lack some data from the battle since some data is not available to your game client during a match.
Problem Report files (file extension: .dmp) are files generated when the War Thunder client crashes. They contain a memory image of the point when the War Thunder executable has stopped working and thus vital information for the technical administration to identify the reason for the unexpected termination of the program.
