Normally for smoothest frame rates you would configure to sync
to your monitor's vertical refresh signal. This is card/platform
dependent ... for instance with Linux/Nvidia there is
an environment variable you can set to enable this feature.
However, if your monitor is refreshing at 60hz and you can't quite sustain
that with flightgear, you can get smoother frame rates by artificially
throttling yourself to 30hz. Note that once you are about about 24fps, it
is *change* or inconsistancy in frame rate that leads to percieved jerkiness.
You want to do whole divisors of your monitor refresh rate, so if your
display is syncing at 75 hz, you might want to try throttling to 25 hz.
Melchior FRANZ:
The reason: these models are to be added to the scenery, but the
scenery isn't yet set up at this point. The correct order is:
- set up model_lib (needed by the scenery)
- set up scenery (needed by the model manager)
- set up model manager
- Modified the rpm vs. suction formula to hit much more realistic numbers.
We should be seeing just over 4 inhg at idle and approaching 5 inhg at
full throttle.
slave to a specific frame rate (i.e. 30hz). This is potentially desireable
if you are running on the ragged edge between 30/60 hz ...
It would be nice at some point to make the code a bit more flexible and
configurable so it could be activated from the command line or preferences
file.
builds the ILS database from several sources and uses an external compiled
utility to crunch the math to straighten out the approaches whenever we can
match them to specific runway headings and threshold locations. This should
be *always* but our runway data is horribly outdated so that needs to be
updated soon to get into sync.
to doing random ground cover objects. This is still in it's embrionic
state so don't expect this to do anything useful or interesting yet.
It shouldn't hurt anything though either.
TITLE: Using delete [] versus delete
The extra "[]" warns the compiler that there is a whole array of objects here so that P's destructor must be called on each element of the array rather than just on P itself (which would be equivalent to the first element only).
