According to the TGC developer they do have real time physics:Yea, the trajectory numbers that TGC is getting is real time, but when you hit the ball, the game has decided a canned response on where the ball is going to land. In PG the ball is hit and the finish position isn't decided till the ball comes to rest. I'm not an expert, but it seems TGC uses real time measurement, but no real time physics.
"I’ve had quite a few PM’s this week about our physics system in the game and questions about whether we will be moving towards an ‘Emergent Physics’ system. From what I understand this is a real time physics system that affects the ball in real time, rather than predicting everything up front and forcing the ball along a path that is predetermined. Well there is good news for you and us, because we don’t have to do any work. Our game already does this. Everything is happening in real time, look how many times John has to correct himself."

it's debatable as to which golf game has the most realistic physics, but IMO both games for the most part have fairly realistic physics.
