Title : Steady Delta Time Routine
Author : Chroma
Posted : 1+ years ago

Description : Delta time differs from frame to frame. This routine stabilizes the delta time for more accurate delta time based movment. While working on Luftwaffe Ace 1946, I noticed this was a big problem because all objects are moved on delta time. This wipes it out and works great for me!
