thanks for explaining to me those things, it really helped me.  now I implementing extrapolation using linear velocity, orientation and position like on here gafferongames.com/post/state_synchronization/ I'm little confused if I want to extrapolate from a known position, velocity and orientation forward 8 tick ahead, how could I do that, any simple example? should I start another post about extrapolation?

Easiest is to extrapolate by running simulation 8 times, especially if collision detection matters.

 

Will the entire scene be affected ? I was thinking about that but others objects will be 8 times ahead too, I'd like to find a way to just run simulation 8 times on that object that needs extrapolation.
