A google search on flightgear and frame rate gave me a posting that suggested trying these options that have been shown to increase frame rate by ~300% (over default settings, as tested on SGI):
--control=mouse --disable-intro-music --disable-random-objects --disable-sound --disable-hud-3d --disable-specular-highlight --fog-fastest --model-hz=60 --geometry=800x600 --visibility=10000.0 --fov=50 --prop:/sim/rendering/static-lod/detailed=500 --prop:/sim/rendering/static-lod/rough=5000 --prop:/sim/rendering/static-lod/bare=15000 --prop:/environment/clouds/layer[1]/coverage="clear" --log-level=alert After doing some testing on the first group above, I note that the geometry seems to be the only parameter that increases frame rate for me. I had been using --geometry=1400x1020 on my Dell laptop (1.4 GHz processor, 2 GB RAM, NVIDIA card), giving about 7 fps on runway. Using 800x600 increases rate to just over 20 fps. I'm wondering if the other ones (specular-highlight, random-objects, model-hz) are known to cause big differences in frame rate. Also, what about the second group (--prop:)? I really don't understand them too much. Lastly, should the following work to show frame rate on startup? Didn't work for me and gave no error: --prop:/sim/hud/draw-fps="true" Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
