MUST be calculated EVERY frame to average itself out, and give real readings.
var fps=0;
...
fps = 0.9*fps+0.1/time_frame;

I tryed the code in the example below;
while(1)
{
//calculate fps
fps = 0.9*fps+0.1/time_frame;
if(fps < 35)
{
camera.clip_far = 3000;
camera.fog_start = 1000;
camera.fog_end = 2000;
}
else
{
camera.clip_far = 12000;
camera.fog_start = 9000;
camera.fog_end = 11000;
}
wait(1);
}
The problem is that my digits return 2, while [f11]-panel returns 40 (the fps_max value)
digits = 0,0,3,_a4font,1,fps;

it uses a factor 16 in the digits on dbg panel use
digits = 0,0,3,_a4font,16,fps;

Can you explain it a bit closer, why it has to be used with a exact factor of 16?

Doh! Good catch MrGuest, I missed that bit....
Sorry Rackscha my bad for sloppy plagarism of 3DGS's 'default.c' coding.
Here is a corrected version with has the factoring built-in.
fps = 0.9*fps+1.6/time_frame;
Just replace the calculation line in your code with this and it will work.
No other changes, and leave your digits as digits = 0,0,3,_a4font,1,fps;
As for my original formula (which I stole from the debug-panel in "default.c'),
I dont know WHY its done with a scale factor of 16, but it just is, and I missed that part.

The frame cycle is measured in ticks. A tick is a 16th of a second. You have to multiply by 16 to get the value in seconds. 16 is the maximum range of the fps_min variable.
