Hi Martin,
Have you checked whether in preferences.xml you have the following
<traffic-manager>
<enabled type="bool">true</enabled>
</traffic-manager>
<ai>
<enabled type="bool">true</enabled>
<!-- scenario>nimitz_demo</scenario -->
<!-- <scenario>aircraft_demo</scenario> -->
</ai>
if so, you should set traffic-manager/enabled to false.
Next, you could also check using the property browser if any aircraft are
listed in /ai/models.
However, I do have to add that, while I cannot rule out a performance decrease
from the new traffic features, I would consider it unlikely, for a number of
reasons, that this is what's troubling you. First, and formost, the new
taxiway follow code only works at EHAM, but there is no traffic yet for this
airport (unless the KLM schedules are uncommented data/Traffic/fgtraffic.xml,
(you might want to check). Secondly, even when you are flying within a
relatively small distance of EHAM, currently set at 150 km. Thirdly, the
traffic manager is still disabled by default, so the new code shouldn't run,
unless you specifically activate it. Fourth and final, the new code doesn't
run on a frame to frame basis, but mainly only when a new taxiroute is
requested. So while I can imagine that this would result in an occasional
pause on slower machines, it should not result in a continuous performance
decrease.
Unless all three conditions above are satisfied, the new code doesn't run.
It does seem that there was another update yesterday, related to a fix in ssg.
(See the email conversation between Matthias Frolich and Melchior Franz,
yesterday evening). While I have not tested this, it might be possible that
this is causing some slowdown, because this patch seems to run on a frame to
frame basis.
Please let me know if the traffic-manager is enabled, and then I hope I can
give you some more assistance in getting your system up to speed again.
Cheers,
Durk
