Known Issues

• The in-game news feed references the latest Windows version, rather than the actual port version. This information may not be applicable to the port version.
• Potential Out Of Memory crashes when playing for longer periods of time (5+ hours)
• AMD OpenGL drivers have trouble handling FSAA for vegetation (white outlines). It is being addressed, but AMD drivers below version 15.5 are not supported currently.

• Minor Linux OpenAL sound issues (occasional mild static or stuttering in dialogues and intense firefights)
• Potential Windows 10 compatibility issues in the 1.42 legacyPorts branch
