i want to log the average framerate of my game.. not the lowest + the highest / 2 either..the actual average. the only thing i could think of was to calculate the actual average every single frame.. but that''s alot of division (read: slow). is there a better way? or am i best of going with the division routes. -eldee ;another space monkey; [ Forced Evolution Studios ]

Well, you don´t need to do it every single frame.
Create a variable that hold the sum of your frame rate every second and other that indicates the time of your aplication since it was started, at the exit you can calculate the average frame rate.

Hope this helps

Hundreds of thousands? Go up a few more magnetudes...

Death of one is a tragedy, death of a million is just a statistic.

i''m not sure, but i think a floatingpoint division takes about 30 cycles.... anyway as mentioned before, u probably have a lot of other divisions, and one more per frame wouldnt hurt

*cry* On our computers we can do hundred of millions of divisions per second...

Come on, doing a few thousands per frame wouldn''t even slow it down by a millisecond..
