When the simulation starts I get 15 FPS which is normal on that PC.
Once I circuit and turn towards the open sea, the frame rate drops
suddenly to 3 FPS, which is quite harder to pilot. Turning the plane
back towards plain land restores the frame rate but only after
several seconds (maybe this is not a matter of time but of what's
displayed). I didn't ask for random objects, 3D clouds or any such
special features.
This is probably becuase your hardware can't handle the high number of
*static* scenery objects in down-town Wan Fransisco (near the bay
bridge). You could try to limit this effect a bit by specifying:
-prop:/sim/rendering/static-lod/detailed=500
--prop:/sim/rendering/static-lod/rough=5000
--prop:/sim/rendering/static-lod/bare=15000
I found no way to add these parameters to the command line. The Windows
Me MS-DOS window did not allow me to type more than two lines of text
for a command.
The best solution I found is to fly using a little 800x600 window. I
still get FPS freezes but very short, merely hickups. Also they don't
occur at the same place neither heading the same direction.
You can alter you preferences.xml file, or use the "Advanced" section of fgrun
to set --prop options.
OK. Thanks. I used the "Advanced" option. Alas the --props change
nothing.
A 1024x768 window yields FPS strikes in-between the 800x600 window and
the 1280x1024 window.
Disabling display features doesn't change the problem. Neither bringing
the fog closer. The FPS suddenly falls low then restores.
I made sure I'm using the latest nVidia graphic drivers.
