I'm having a strange problem that may be linked to this.
Now when I start at KSFO, looking forward, I'm getting < 1fps.
Same with the heli & chase views. If I switch to the tower it's
the same until I start zooming in. At around 15 deg fov the
frame rate jumps up to around 25-30 fps. Switch back to the
chase view and it's back down to < 1 fps.
Incidentally, the a/c I'm checking with has slowly revolving
props so I can see the changes in frame rate very clearly.
Anyway, back to the chase view and rotate the view around using
shift and the num-pad. Shift-9 is fine - > 20 fps, shift-6 < 1
fps, shift-3 > 20 fps. From 2 through to 8 are all < 1 fps.
Try KJFK. Here only one view gives problems (can't remember
exactly which one now though). It's also apparent while using
the mouse to change the view.
Back to KSFO, tower view and try a take off - > 20 fps. Try
chase view and < 1 fps until just after the last of the white
blocks on the runway (sorry, don't know their proper name) when
it jumps to > 20 fps.
It'll also happen while I'm flying - I flew out over downtown SFO
and was heading back to KSFO at > 20 fps but then it dropped
back down to < 1fps.
I'm guessing that it's due to a scenery or random object problem,
as it also happened at KJFK where there're no custom scenery
objects, but I can't identify what it can be.
Any ideas anyone? FG is pretty unusable for me atm.
FWIW, glxgears gives > 3900 fps here.

I get this problem also with any of the Nvidia Linux 7xxx drivers. Other
programs like torcs still run fine, only fgfs seems to be affected.
I used to get 30 to 40 fps at KSFO. If I look down at the cockpit (still
at KSFO) or up at the sky or I look to the right more than about 15
degrees or to the left at about 90 degrees it runs at normal speed. Look
straight ahead and I get about 1 frame every five seconds. Same result
at KEMT.
Have looked through the nvidia forums but haven't seen anyone complain
of problems like this.
