Hi Steven,

This 360Hz concept has been around with iRacing for a very long time in various forms. In short, there is no advantage to you. iRacing would be sending 1 current steering force value along with 5 historical values (from earlier moments in time). 

They say this:

Basically we run our physics at 60 Hz (based on the real world clock) but internally we run the physics in an inner loop at 360 Hz (based on the sim clock). So we can't actually update the wheel more than 60 times a second, although we do have data points available at 360 Hz.

This is a back door that allows us to send that 360 Hz signal to the wheel 60 times a second, then the wheel firmware can play back those samples, with the appropriate delays, to recreate the 360 Hz signal. This adds 16 ms of latency but gives a nice kick in frequency, it is a trade off. This is really no different than irFFB, other than it is faster (less latency) and it is baked into the sim so you don't have to run a separate tool to make it work.

The AccuForce already upsamples their 60Hz data to far beyond 360Hz in firmware at a hardware level without the lag induced by their new feature.
