Yeah, from the testing I have done games like AH3 do not need the higher refresh rates. If we had the FPS experience here (it may happen at some point, but not now), then 120-144Hz would be really good. It might also require that hitech add motion blur to the game, so that people don't experience motion sickness. We are already beginning to see some of that in the VR experience.
That said, it is also possible that higher speeds near the ground, or high velocity vehicles could incorporate peripheral vision imbalances, which can cause queasiness and motion illness.
Something for further investigation I think. Just ask yourself if you play mostly FPS type games (higher refresh is best), or flight sim type simulations (60 fps).
