Ouch! But that's much more than I could have hoped in terms of information. Thank you very much! What would be
the visibility for this test? They currently max at 7 NM.
All default settings.
I was most surprised with:
Onyx2 IR2E R10K/250 4MB L2 4RM9/64MB: 4.79
I have to state that I took this table because it compares quite accurately with the data sent to me (by email). So the actual numbers might differ, but the reports I have had were *very* close.
This table is based on performance reports from FlightGear users who have sgi equipment. But be aware that this is about the default startup position (stationary at KSFO) which seems a bit heavy on the scenery for alder hardware.
Actually, although they want the Bay Area some time in the future, their current database covers South Western U.S. but
the projection is a poorly implemented Lambert-Conformal Conic projection. So, they really only have database latitudinally
along a thin strip along the middle. They have only 2 airports with even a handful of buildings. Their database does, however,
have lineals (roads, rivers, railroads).
There is a configuration file that can be used to fine tune FlightGear a bit on older video hardware which might give a performance improvement up to 500%.
I saw that. What's the units for visibililty? The file shows 10000.0, but what are the units?
It's in meters.
BTW, how do I determine what my visibility is? And, how do I reduce the fog at far clipping plane?
You could use 'z' and 'Z' to change the fog settings.
Yea, that changes the settings but how do I know what the value is set to? Thanks!!!
Use the property browser and search for /environment/visibility-m
