Hello L.Spiro
I was the one pestering you on the Fixed-timestep tutorial. I made a reply there today but looks like it doesn't show up so i will post it here if you don't mind?
I can't get this to work correctly, and i made an bare minimal win32/dx9 project that shows the problem, if you can find time to look at and help me?

There must be problem in my logic as i tried exactly just like you showed in your tutorial. Movement speed of the objects are very different when i enable vsync (D3DPRESENT_INTERVAL_ONE) and when is off (D3DPRESENT_INTERVAL_IMMEDIATE).
Thank you for your time and patience.
