Same speed on all machines and Tweening

BlitzMax Forums/BlitzMax Beginners Area/Same speed on all machines and Tweening

Hey, sorry to pop in but im probably as new as christian223 when it comes to gameloops.
i used this code also http://www.blitzmax.com/codearcs/codearcs.php?code=2039

having put all my drawing stuff in the render group, and all the login in the update group. i wonder, what is the tweening for?? i know what it does, but because i have fixed my UPDATE_FREQUENCY on 50 it doesnt really use the tweening, only when i go very low, to lets say <10 it uses tweening, but whats the point of that???? i fix it on 50?! so why did this guy build the tweening in?

To me its like:
UPDATE_FREQUENCY =50
if UPDATE_FREQUENCY  <10 then
'do lots of complicated stuff, which i could as well just rip out of it
end if
