I just loaded/compiled FlightGear on my system. I have a AMD Athlon running at 1.1 gig, 1 meg of RAM. The OS is Fedora Core 3. Video card is a NVidia GeForce 2 with 32 megs of video RAM. The problem is the sim will launch but runs too slow to play. The CPU meter is showing 100% useage. I ran 'top' and found that the fgfs process is only using 2-3% of the CPU but 'X' is using everything left, >95%. Is there a way to tune flightgear so it doesn't use all of the processor cycles?

I went back and reinstalled the Nvidia drivers for Linux. FlightGear fired up and was working much better. However, as I was looking at menu items it crashed on me. Now when I try to launch it from /usr/local/FlightGear/bin I get this error../fgfs: error while loading shared libraries: libopenal.so.0: cannot open shared object file: No such file or directoryI found libopenal.so.0 in /usr/local/lib/libopenal.so.0.Is there a link I need to make? When I try to run it out of /usr/bin I get:freeglut (fgfs): OpenGL GLX extension not supported by display ':0.0'I have recompiled a couple of times and gotten nowhere.

Have you looked at this forum?http://www.linuxquestions.org/questions/sh...threadid=321212Might provide some insight.

I ended up reinstalling the Nvidia linux drivers and got it up and running. One more problem. I can run the binary (./fgfs) but when I try to run the runfgfs.bat file I can't get it to work. I have tun it as my user and as root and get errors about not having permission. What exactly does runfgfs.bat do?
