Re: [Flightgear-devel] Speed question?

[Matevz Jekovec]

5) Around the default KFSO, the framerate is way slower than in e.g. Slovenia. Is there any way to fix that (I know there are way more objects, but still I think it should be faster than 6 FPS when looking to the city or airfield) Is that fps in cockpit view or chase view? I get that sort of fps in chase view at KSFO too, but if in chase view there's also the a/c texture overhead as well. KSFO is pretty heavy especially if you've still got the high res textures. In 3d cockpit view. That leads me to another question. Is there any way we can optimize the graphic engine, not to be so slow in 3d cockpit view? I know we had similar problems with the engine in Falcon, but were never solved due to untouchable source code later (license issues). Why does it work so slow, when viewing a 3D object from close distance anyway? What about the outer views: Does FlightGear use seperated 3D cockpit files for inner view or does it use aircraft's model cockpit? In Falcon, we had completely different files for 3D cockpit and aircaft model ... I'm asking this, because the cockpit of every aircraft can be as complex as all the other parts of the aircraft together. So when showing, say 10 aircrafts together someday with their own intelligence and properties, framerate will very drop but you'll hardly see the canopies of the aircrafts, let alone the inner cockpits. I think breaking free the 3D cockpit from the aircraft model isn't a bad idea. Has anyone give this a thought already?
