Time to polish this a bit and making it look like there's actually something projected onto a glass surface:

Sun glare brings out the faint glass scratches better:

Wow it starting to look really pretty now! Give the font I recommended a shot; it will fit nicely :). Does ALS support Bloom? Because just a subtle touch of bloom on the symbology can also be worth trying.

Regards!

I can't - the license from the download page which I get when I google the font name (1001fonts.com) is clearly not GPL compatible, so it's off-limits for FG.

Sh*t you're right. Try this one:

It's covered by Open Font Licence and fits just right

I did some tweaks to the ADI (more agressive culling of points, change of the update strategy,...) today as well as clocking down of some non-trajectory relevant systems calculations using the execrate tag. Please test whether this brings more (and more even) framerate.

I guess I'll also try to by-pass canvas code to update plots and use setprop() rather than props.nas for the performance-critical operations. This should give another boost...

Yep, seems to have worked here...

It appears that I gained 3-4 fps. I am getting a solid 7-8 fps VS the previous 4-7 on my core-duo CPU/nVidia 640.

Putting the figures into perspective, it's almost a 100% boost! :D

I'm not at home at the moment, I will try next week. But if just the shuttering is gone, that would already be a big step.

I know too little about your setup, so I won't promise 'gone', but certainly 'much reduced' should be the case (by my best estimate, the ADI ought to update a factor 3-4 faster now).

Did something change with the Speed Brake? The "s" key no longer opens it unconditionally. It closes immediately after letting go of the "s" key.

Yeah - AUTO now actually works on approach. You have to either trust it or use the pushbutton to switch it off.

I think I've now actually managed to get the flare transition guidance logic right - so if you fly by the flare triangles from outer to inner glideslope, you should come out more or less good for a few seconds of inner glideslope before final flare.

About the fps , I did notice an improvement, now the ADI setting has almost no impact on frames, and the performance I'm getting with the shuttle is near to what I get with the stock C182 in a similar scenario (which is far from impressive, but I just can't squeeze more fps out of Flightgear). Good job!

Would you mind giving me the numbers (visibility set if close to the ground, rendering quality settings) as well as frame rate and frame delay (you can enable those counters under view options in the GUI).

Also, could you go to HUD view and point the Shuttle at the sky when in orbit (i.e. no rendering load) and tell me that framerate (it's nearly pure CPU load under these conditions)?

I will gradually clock down more JSBSim, and a fast system might be the best benchmark to gauge the effect of this.
