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. A difference in framerate due to Specular highlight and/or random objects depends on the Video chipset (GPU) whether it makes a difference or not. A difference in framerate due to changes in the model-hz depends on the main processor (CPU). I would not recommend using this option unless it _really_ makes a difference. Also, what about the second group (--prop:)? I really don't understand them too much. It specifies the complexity of static scenery models at three different stages (Level Of Detail; LOD). Setting them to lower numbers should increase the framerate and setting the numbers higher would improve visible accuracy. The last of those specify not to display any cloud cover. 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 This is only for showing the framerate in the alternative HUD.

As for showing frame rate, it is a bit inconsistent, IMO, that one can put frame rate in lower right corner of normal c172 cockpit view by clicking File - Browse Internal Properties - sim - hud - draw-fps[0] and setting to true. ^^^ Is there no way to get frame rate to appear (in normal view, not HUD) on startup?

The FPS is shown in the bottom right side of the screen, not in the actual heads-up area. The property is definitely correct; cutting and pasting exactly that argument onto my command line shows the FPS clear as day.

Andy I just noticed the characters 'true' when I used the menu to check the /sim/hud/draw-fps string. So I tried using --prop:/sim/hud/draw-fps=true without the double quotes on true and I got the frame rate displayed in bottom right corner. Excellent! A previous post mentioned that setting this property in this way is only for showing the framerate in the alternative HUD. Can't say I know what is the alternative HUD. Mike __ Yahoo!
