Known issues

• Some systems have incorrectly restored the permissions on the files. The application attempts to write a log.txt to the main directory. If it is unable to do this, you will get an error saying to check the log.txt file (which it cannot write). Make sure that the main directory is writable.
• Failed to set display mode. The available video modes listed are those supported by the video card and not necessarily the monitor. Choose a display mode that is supported by the monitor.
• Some video cards / drivers are not able to go into full screen mode with the application. Please send support@realityinteractive.com a detailed description of your video hardware and driver versions along with the hs_error_pidXXX file. The error (in a hs_error_pidXXX file) will typically look like:

• Some sounds are clipped (specifically, the nailguns).
• Ambient (not static) sounds are not being played.
• Multiple sounds from the same source will play simultaneously rather than stopping the previous sound and starting the new one. This will cause distorted sounds at times.
• No blending when underwater.
• No color shift when player is hit.
• Decals may have z-fighting on some video cards.
• Every so often (just often enough so as to be annoyingly un-reproducable) a mesh (alias) model's frame data will not have loaded correctly causing a JVM crash due to a bad pointer. If it occurs, just run it again. It has never occurred more than once (adding to its un-reproducability). The error (which may be in a hs_err_pidXXX file) looks something like:

Linux Known Issues

• LWJGL will grab hold of the mouse and not let go (well, it's actually X that is doing this). This may cause problems if the application loses focus. Be prepared to kill the application via a remote terminal if you are concerned that another application may gain focus. This will occur in both windowed and non-windowed modes. (alt+tab will correctly release the mouse on Windows.)
• Refer to the LWJGL forums for driver and version issues.
• It is common to need to run the application as root to have the necessary permissions to use OpenGL under X.
• Random sounds will continually loop.

Unknown Issues

• Currently, the system has not been tested with multiple video cards. However, it is known to work correctly with dual head displays.
• If your audio card is a rare or unknown type, there may be issues with Java Sound playing correctly. If this is the case, disable sound with "-nosound" or un-check the sound option on the launcher window.
