With a working OpenGL/DRI setup you typically get far more
than 1000 fps with 'glxgears'. Please run 'glxinfo' or
'gl-info' - whatever you have on your machine - and have a
closer look at the OpenGL 'vendor',

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 have also 1fps, but that's with enhanced runway lighting at night ;)
