This subject line is really misleading.

Having no graphics at all makes a big difference. You would not implement a 
solution to your problem as you would "the best way" for a game, and the 
solution you need depends on your actual requirements. 

"update the position in small increments many times per second" — 
What does "many" mean to you? What level of accuracy do you need? How should 
this interact with the main thread, etc?
