System Crashes

If running FlightGear causes system instablity or even crashes your whole system, it is important to realize that something really is wrong with your whole system and not FlightGear: modern OS generally don't allow userspace applications to affect system stability.

So if you are running a modern OS (such as any more recent version of Windows, Mac OS or Linux) and running FlightGear still affects overall system stability in one way or another, something is likely very wrong with your hardware or software setup. Things specifically to look out for include:

• insufficient free system resources (memory, CPU power) (see Hardware Recommendations)
• driver issues
• insufficient CPU/GPU cooling
• faulty RAM
• computer viruses
