@alphaindigo: I think what you're looking for is temp_step or time_factor. Look them up in the manual, you can calculate the FPS from these variables.

thanks the reason i wanted to know was because i wanted to make the clip_range directly dependent on the fps like this

while(1)
{
clip_range = ([var for fps] *500);
}

any ideas

time_fac*16 - have that.

frame_rate = time_fac*16;

time_fac is merely the reciprocal of the time variable, or raising it to the -1 power:

frame_rate = pow(time, -1)*16;

Edit: Forgot the *16 for the pow() method. As to which is faster, that I don't know, but I suspect time_fac.

thanks i think that might just about do it
